90 Deg VHT Blue Silicone Exhaust Hose Elbow - 2-1/2" ID, w/o Clamps

Trident silicone and EPDM rubber elbows provide flexible connectors for marine wet exhaust systems. They offer much greater tolerance to heat, misalignment, engine movement and vibration than rigid connections, with significant savings in cost, parts, labor and space.

These 290V Series exhaust elbows are made of Very High Temperature (VHT) Blue Silicone* blended with EPDM rubber with no textile reinforcement. They are molded with a smooth bore and cover; except elbows of 6” ID and larger have molded reinforcing ribs on the outside.

This synthetic rubber blend is rated for use up to 350°F (177°C) maximum, continuous duty, and comes with a substantial 10-year warrany.
The elbows have excellent resistance to ozone, salt water, diesel fumes and splash, cold, heat, and aging.
They exceed SAE J2006-R1 and ABYC & NMMA P-1 exhaust standards.

• Blue silicone/EPDM blended rubber elbows - rated -65°F to +350°F maximum
• 290V elbows are available with 2" to 10" internal diameters
• Inlets/outlets are long enough to accept two hose clamps
• Part numbers ending in "SS" come with (4) wide stainless steel T-bolt hose clamps
• Part numbers containing EL have one leg 3" longer than the other


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.
