Trident Marine 3" ID 90-Degree EPDM Black Rubber Molded Wet Exhaust Elbow with 4 T-Bolt Clamps - TRL-390-S/S

Key Performance Features

• High-Temp EPDM Rubber: Specially formulated to withstand continuous temperatures up to 280°F (138°C). It is resistant to ozone, salt water, and the acidic nature of exhaust byproducts.

• T-Bolt Clamps Included: This "S/S" kit includes four (4) 316 Stainless Steel T-Bolt clamps. T-bolt clamps provide significantly more uniform sealing pressure than standard worm-gear clamps, which is critical for preventing leaks in high-vibration exhaust zones.

• Molded for Precision: The 90-degree bend is molded to maintain a consistent 3-inch internal diameter (ID) throughout the curve. This ensures maximum exhaust flow and prevents "bottlenecking" backpressure.

• Wire Reinforcement: Designed with high-strength fabric and/or wire reinforcement (depending on the specific layup) to prevent the elbow from collapsing or ballooning under pressure.

• Standards Compliance: Meets or exceeds SAE J2006 standards for marine wet exhaust systems.

Installation & Maintenance Tips

• Proper Alignment: Ensure the exhaust pipes are pushed fully into the elbow before tightening. The pipe should seat past the first T-bolt clamp for a secure, leak-proof seal.

• The "Double-Clamp" Rule: Always use two clamps per side (as provided in this kit). Position the clamps so their bolts are 180 degrees apart to provide the most balanced pressure on the rubber.

• Inspection: Check your exhaust elbows annually for "bulging" or cracks. EPDM is durable, but extreme overheat events (like a failed raw water impeller) can char the interior of the rubber, making it brittle and prone to failure.

• Lubrication: If the fit is tight, use a tiny amount of dish soap and water to slide the elbow onto the pipe. Never use oil-based lubricants or grease, as they can degrade the rubber over time.
