Blue Silicone Wet Exhaust Hose - Very Hi-Temp, 4" ID x 3 ft. Long

Trident Silicone Marine Wet Exhaust & Water/Coolant Hose is the ultimate in extra thick soft wall silicone quality with very high temperature performance and extra long service life.
Exceeds SAE J2006-R1, and ABYC & NMMA P-1 exhaust standards.

Characteristics of the 202V Series of Reinforced 100% Blue Silicone Exhaust Hose:
Glossy blue, very high temperature, 100% silicone* rubber, which is reinforced with 4 to 6 plies of polyester fabric.
Designed for wet exhaust & higher pressure critical water service.
Available from 1/2" to 16" inside diameter.

• 100% blue silicone rubber - rated -65°F to +350°F maximum, continuous duty, with a 10-year warranty
• Hand built
• Lasts much longer than black rubber exhaust hoses
• Recommend double clamping with stainless steel T-bolt or Constant-Torque hose clamps
• Blue with white stripe


High Temperature Exhaust Hose Color Comparison
• Black exhaust hoses: made from molded, high temperature, black EPDM rubber. Rated -40°F to +250°F maximum continuous, with a 5-year warranty
• Blue exhaust hoses: made from a very high temperature, blue silicone rubber. Rated -65°F to +350°F maximum continuous, with a 10-year warranty
• Red exhaust hoses: made from an extra high temperature, red silicone rubber. Rated -65°F to +500°F maximum continuous, with a 10-year warranty
• Double ply, impervious to oils solvents

The addition of multi-ply fabric reinforcing enhances a hose's pressure resistance for coolant, turbocharger, and other higher pressure applications.


*Silicone rubber's outstanding characteristic is its resistance to higher temperatures, as well as having a longer service life than EPDM. Silicone hose is compatible with water and anti-freeze/coolants.
By comparison, EPDM (Ethylene Propylene Diene Monomer, commonly referred to as EPDM or EPDM rubber) can withstand modestly high temperatures and exhibits excellent resistance to environmental factors such as Ozone, UV, acids, bases, and general weathering.
Neither of these synthetic rubbers is compatible with fuel or oil, so be careful to protect from exposure.

What is marine exhaust hose?

A marine exhaust hose is durable and provides a flexible connection for circulating, transferring, and cooling engine water. It is easy to install, has a long lifespan, and absorbs vibration better than pipe or tubing.
