292V 90 Deg Reinforced VHT Blue Silicone Exhaust Elbow - 2-1/2" Dia, with Clamps
Trident silicone 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 292V Series 90° exhaust elbows are made of 100% Very High Temperature (VHT) Blue Silicone* rubber reinforced with 4 plies polyester fabric. They are hand-built with a smooth bore and cover.
This synthetic rubber 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, saltwater, diesel fumes and splash, cold, heat, and aging.
They exceed SAE J2006-R1 and ABYC & NMMA P-1 exhaust standards.
• Blue silicone rubber elbows - rated -65°F to +350°F maximum
• 292V elbows are available in five sizes with 2" to 4" 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
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.
