Corrugated Silicone Marine Wet Exhaust Hose, 2" ID, (3 ft. Long)

252V Corrugated Very High Temperature Blue Silicone Marine Wet Exhaust Hose is the ultimate in flexible wet exhaust quality with a higher temperature rating, wire reinforcing, extra long service life, and excellent long length bendability.
Its outstanding characteristic is its very high temperature rating as well as its side-to-side structural strength and ability to withstand sharp bends without folding and collapsing like other types of water/exhaust hose.
This ability is not only due to its corrugated structure, but also to its internal helical wire reinforcing with additional strengthening by two spiral plies of of high tenacity polyester fabric.
252V water and exhaust hose is suitable for longer runs and angled connections in applications with exhaust temperatures up to 350° F.

Built of 100% silicone* rubber with an extra thick wall, glossy blue corrugated cover, smooth red inner tube, and a wire helix between 2-ply polyester reinforcement.
Perfect for long wet exhaust runs with bends (engine or genset), and premium raw water and coolant hoses.

• Exceeds SAE J2006-R2, ABYC and NMMA P-1 exhaust standards, as well as EPDM black rubber exhaust hose specs
• 10-year warranty
• Available in 3/4" to 18" internal diameters
• Available in 3, 6, 12 and 60 ft lengths


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

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.
