TRANS-DAPT 4466 3.5-Inch 3-Bolt Collector Gasket

The TRANS-DAPT 4466 collector gasket is designed to help create a reliable seal between compatible exhaust collector components. Its 3.5-inch inside diameter and three-bolt configuration make it a practical replacement for matching collector assemblies, helping reduce exhaust leakage and support consistent system performance. The gasket is sold individually and is suited for automotive exhaust repair and installation applications.
Constructed with a steel core laminate, this collector gasket provides a durable sealing surface that helps withstand the heat and vibration commonly associated with exhaust systems. The 0.063-inch thickness supports proper fitment on compatible flanges while helping compensate for minor surface irregularities during installation. Verify the collector flange pattern, bolt-hole arrangement, and required gasket specifications before ordering.
The TRANS-DAPT 4466 is a direct replacement-style exhaust gasket for applications requiring a three-hole, 3.5-inch collector seal. Its compact design allows straightforward installation when used with properly prepared mating surfaces and suitable fasteners. For best results, remove old gasket material, inspect the flanges for damage or warping, and tighten the fasteners according to the vehicle or component manufacturer’s recommendations.
