There are many manufacturers of marine hoses in the market who offer different types of marine hoses for different purposes. First, you need to identify the type of hose you need and then choose a manufacturer accordingly. You should consider the following checklist when choosing a marine hose manufacturer, especially before purchasing. For example, some manufacturers supply steel fittings, brass fittings, and aluminum fittings in addition to rubber marine hoses.

Choose your marine hose manufacturers based on the following:

1. Materials and quality
2. Service and delivery
3. Pricing and variety

Materials and quality in your marine hoses

The industry&#;s leading boat builders rely on Terraflex marine hoses, especially designed for sea and dock applications.

Commercial boats aren&#;t the only ones that use marine hoses. They can also be used on private motorboats, fishing boats, and yachts. There are a wide variety of marine hoses available in a variety of sizes and materials to handle the needs of each boat. For those looking to find tubing systems suitable for marine vessels like boats or yachts, there are several options available.

As soon as you have defined your needs, review the above checklist to determine if the manufacturer is a good match.

Polyurethane or PVC are excellent materials for marine water hoses since they can last for many years. To be able to handle the harsh conditions of the sea, it should also be resistant to sunlight and have a high degree of abrasion resistance. Hoses made from silicone repel water best as they are resistant to harmful UV rays and have good heat resistance.

Our Marine Hoses are made of 3-ply polyester reinforcement for lasting abrasion resistance, while assuring maximum flexibility. Terraflex Marine hoses are also designed to withstand high pressure usage and are made of food grade, nontoxic, odorless and tasteless, FDA approved inner tubing.

Select from Marine Clear and White Braided hoses and Wash-down hoses, to marine boat speedometer tubing to fuel and lubrication tubing. Our clear reinforced hoses perform well under high working pressure and harsh conditions with an operating temperature of -28C to +65C, and are available with colored thread tracers.

Mind the hose!

Consider what can happen when a hose bursts. If you are lucky, you will only have nuisance repairs to electronics, engine or interior. If fate has it in for you, a defective hose can cause a stink if it&#;s the discharge of the head, cause a fire if it&#;s part of a gas line or even sink your boat if it&#;s connected to a thru-hull fitting. That&#;s why we recommend spending a little more on a high-quality marine hose that offers more durability and better performance in critical applications and why you should inspect your hoses frequently for signs of deterioration.

 

Selection Questions

What fluid or application do you need the hose for?

Your application will determine what kind of hose to purchase. Our selection of hoses encompasses most applications and is available in any length from a foot up. The following is a guide to match hose and application.

Raw Water Hoses

Raw water intake hoses ingest water from outside a boat to cool an engine, flush a toilet, cool an air conditioner or provide a fresh supply of water for fish in bait tanks. Use only hose recommended for &#;below waterline&#; connections. Depending on the application, raw water intake hose will have fabric, PVC or stainless steel spiral reinforcement that resists kinking and prevents the hose from collapsing when for example, an engine pulls a vacuum due to a clogged water intake screen. For engine raw water intake, we recommend Shield's Series-250 or Series-252 hose, both of which are reinforced with a metal wire helix to prevent collapse. For engine coolant circulation, Shields Series-135 hose, which is reinforced with polyester yarn spirals can be a good choice&#;however care must be taken not to exceed the minimum bend radius and the temperature rating of the hose. For an overview of hose applications, see the hose application tables below.

Drain Hoses

Drainage hose for cockpit, sink or shower needs to be flexible with strong walls and resistance against kinks and abrasions, but since they are under positive pressure, they generally don't require helical wire reinforcement..

Freshwater Supply Hoses

Potable water hoses must be made of FDA-approved, non-toxic materials so they won&#;t cause bad taste in drinking water supplies. Pressurized freshwater systems must use reinforced hose to withstand pump pressure (approx. 40&#;60PSI).  For fill and vent hoses in water tanks, extra-heavy-duty sanitation/water hose should be used, while reinforced rubber hose is the best choice for hot water up to 140°F.

Alternatively, you may use a reinforced vinyl hose reinforced with nylon braid. Examples include: Series 162 (polyester reinforced clear PVC hose), FDA approved; Series 140 VAC Standard (steel wire reinforced PVC hose); and Series 148 Multi-Purpose (vinyl helix hose) FDA approved, ideal for critical drain and fill applications.

Bilge Pump Hoses

Bilge pump hoses typically use corrugated polyethylene with molded cuffs because it is flexible, economical and resists oil, solvents and other waste that collects in the bilge. For better flow you should choose a hose with a smooth bore, abrasion-resistant cover and good anti-kink flexibility. Examples include: Series 148 Multi-Purpose (smooth-walled vinyl helix hose) FDA approved, ideal for critical drain and fill applications, and Shields Multiflex Hose (Series 141). Of the corrugated hoses, the best is Shields VAC Standard (Series 140) and Bilgeflex (Series 120).

Sanitation System Hoses

Sanitation hose has to be tough, flexible and resistant to odors and toilet chemicals. Choose hose with a smooth bore, heavy wall and specifically labeled for marine sanitation use. There are two choices: white vinyl hose and sanitation hose. Both will eventually smell. We recommend only smooth interior wall hose because corrugated types trap waste and restrict flow. Rigid PVC does not pass odors but is stiffer and more difficult to route and does not connect directly to pumps and thru-hulls. Still it is possible to plumb part of the system with rigid PVC, switching to hose where necessary.

 

What to Look For When Choosing Marine Hose

Reinforcement: Many hoses have reinforcement in the walls for strength and rigidity, and to prevent collapse or expansion under pressure. The reinforcements can be wire, yarn spiral or PVC/vinyl helix.

Burst strength: Hose used for discharge lines has to resist pressure. This so-called burst strength, measured in pounds per square inch (psi) depends on product design and diameter; small diameter hoses have greater burst strengths. Hose with multiple plies or helical reinforcement has greater pressure limits, which is important for pressurized water or exhaust applications.

Vacuum rating: Hose on the intake side has to withstand suction, a property that is measured with a so-called vacuum rating. Intake hose should have a vacuum rating of 20 or higher.

Temperature range: Mostly critical for engine cooling hose, but might also be important for pressurized hot water systems.

FDA-approval: Hose used in potable (drinking) water systems must be constructed from safe, non-toxic materials that are contamination- and corrosion-free.

Bend radius: For proper installation a hose should not be bent more than the minimum bend radius recommended by the manufacturer to avoid kinks and breakage. Especially important for sewage lines and bilge pump applications.

 

Sometimes a lubricant is needed to install a hose onto a fitting.

Choosing the Right Hose Diameter

Hoses are sized by their inside diameter (ID). Hose fittings are labeled based upon the ID of the hose they fit. In other words, the outside diameter of a 1/2" barbed elbow is liable to measure slightly greater than 1/2", but it will fit 1/2" ID. hose just fine. Smooth bore hose is recommended for all applications, since corrugated hose can reduce flow by as much as 30%. Hose needs to be matched to the fittings on pump, through-hull, deck fill, tank, etc. See below for some sizing guidelines. Some popular diameters by application:

• Bilge pumps: 3/4", 1 1/8", 1 1/2", or 2"
• Deck fill/discharge: 1 1/2"
• Gasoline feed: 1/4" to 3/8" depending on engine size.

Choosing Hose Clamps

Marine hose clamps are stainless bands that compress hose around barbed fittings. They can be made from a variety of metals, but quality ones are all stainless steel, including the screw, band, and other parts. T-Bolt hose clamps are much stronger and have a 360° clamping surface. They are used in applications with high pressure, heat, vibration, or other severe requirements, like exhaust systems. Two clamps are recommended for below-waterline connections. Thru-hulls, hose lube & sealant, etc. may be necessary to make a hose fit and complete your marine plumbing system.

Installation tips

• Most boats use flexible vinyl or rubber hose and barbed fittings secured by hose clamps. You may find it easier to install hoses over barbed fittings if you place the hose in hot water first and use liquid soap as a lubricant.
• Threaded fittings should be wrapped with thin plastic Teflon tape or some other sealing liquid prior to assembly, to seal tiny gaps in the threaded connection.
• In household applications, plastic pipe and fittings are solvent welded with PVC pipe cement. This technique is not recommended on boats because pounding and vibration might cause fatigue and failure of these connections.
• Use double hose clamps on hose to pipe connections below the waterline for extra security. Make sure to use hose barbs long enough to give both clamps some gripping surface.
• Connect fittings of the same material within a system because thread styles and inter-thread distances will match. In addition, rigid bronze fittings have been known to split weaker plastic fittings when they are being tightened.
• Normal green color is not a problem on an aging bronze fitting. A pink or red color, on the other hand, is an indication of galvanic corrosion.
