Remflex 3" Universal Exhaust Collector Gasket Set of 2 — Flexible Graphite, 3-bolt 3-3/8" spacing

Remflex 8002 is a set of two universal 3" exhaust collector gaskets made from 100% flexible graphite, engineered to seal warped flange surfaces and prevent exhaust leaks.

When exhaust components heat and cool repeatedly, mating flanges — especially aluminum heads to steel headers — can develop gaps, pits or warpage. The Remflex 8002 gaskets are built to compress and conform, filling irregularities in the flange face so you get a consistent seal without composite binders that harden over time.

How does this gasket stop leaks on warped flanges?

The Remflex 8002 gasket uses pure flexible graphite that compresses under bolt load to create a tight seal even when flange faces are uneven. Its material properties maintain conformity through thermal cycles without shrinking or becoming brittle.

• 100% flexible graphite construction resists shrinkage and hardening
• Designed to crush approximately 50% to adapt to flange irregularities
• Seals pits and gaps up to 1/16" in the flange surface
• Works with dissimilar metals like aluminum heads and steel headers

What are the exact fit and dimensional details I need to know?

This gasket set is sized for a 3" pipe collector flange and includes two gaskets for two mating flanges or a replacement pair. The pattern is a universal 3-bolt design with 3-3/8" bolt hole spacing to match common collector configurations.

• Fits 3" exhaust pipe / collector flange
• 3-bolt pattern with 3-3/8" bolt hole center-to-center spacing
• Standard material thickness: 1/8" (before compression)
• Sold as a set of 2 gaskets for dual-flange applications

How durable is the gasket under repeated heating and cooling?

Because the Remflex 8002 contains no rubber binders or composite fillers, it resists the common failure modes of shrinkage and hardening. The graphite maintains flexibility over many thermal cycles, which reduces the need for repeated retightening of flange bolts.

• No rubber binders to degrade with heat or time
• Flexible graphite preserves compressibility through temperature swings
• Designed to hold seal integrity without frequent re-torquing
• Suitable for exhaust systems subject to wide temperature ranges

Can I use these gaskets on different vehicle exhaust setups?

Yes—the universal dimensions and flexible graphite material make the Remflex 8002 adaptable to many collector flanges and aftermarket headers. Confirm the 3" pipe size and 3-bolt spacing match your flange to ensure a proper fit.

• Compatible with many aftermarket headers and OEM collectors of the same pattern
• Best for 3" pipe systems and 3-bolt collector flanges
• Ideal where aluminum-to-steel mating surfaces create gap challenges
• Useful as replacement gaskets or during exhaust upgrades

Who is this for: The Remflex 8002 Universal Exhaust Gasket (Set of 2) is aimed at mechanics, home garage enthusiasts and performance installers who need a reliable, long-lasting seal for 3" collector flanges. If you work with headers, manifolds or exhaust collectors that show flange warpage, pitting or gaps—especially where aluminum and steel meet—these graphite gaskets offer a practical, maintenance-reducing solution without composite binders that degrade over time.
