Remflex 8002 Universal 3" Exhaust Collector Flange Gasket Set of 2 — 100% Flexible Graphite, 1/8" Thick

Remflex 8002 is a pair of universal 3" exhaust collector flange gaskets made from 100% flexible graphite designed to seal warped or uneven exhaust flanges reliably.

This Remflex 8002 set includes two universal gaskets engineered for 3" pipe collector flanges with three bolt holes and 3-3/8" bolt hole spacing. Manufactured from pure flexible graphite at a standard 1/8" thickness, these gaskets compress to conform to irregular flange faces created by differential thermal expansion between aluminum heads and steel headers. The material is free of rubber binders or composite fillers so it resists shrinkage and hardening over time, maintaining a long-lasting gas tight seal without repeated retorquing.

How does the Remflex 8002 gasket stop exhaust leaks?

Flexible graphite seals by compressing into surface irregularities and filling pits or gaps that form when flanges warp under heat cycles. Its 1/8" starting thickness is designed to crush approximately 50%, creating a tight seal across uneven surfaces up to 1/16" deep.

• Material: 100% flexible graphite for heat tolerance and conformability
• Compression: designed to crush 50% to fill gaps up to 1/16"
• Thickness: standard 1/8" that compresses to match flange irregularities

Will this gasket fit my vehicle’s exhaust flange?

The 8002 is a universal gasket sized for 3" exhaust pipe collector flanges with three bolt holes and 3-3/8" bolt hole spacing, making it compatible with many headers, manifolds, and collector joints. Always check your flange diameter and bolt spacing to confirm fit before installation.

• Pipe size: compatible with 3" collector flanges
• Bolt pattern: three bolt holes with 3-3/8" spacing
• Sold as: set of two gaskets for dual-joint repairs or spares

What advantages does flexible graphite offer over composite gaskets?

Flexible graphite provides high temperature resilience without rubber or other binders that can dry out and shrink. That stability reduces the need for repeat tightening and keeps the flange joint sealed throughout repeated heating and cooling cycles.

• No rubber binders or composites that harden over time
• Retains compressibility after many heat cycles for a longer-lived seal
• Resists thermal degradation common to binder-containing gaskets

How should I install the Remflex 8002 gaskets for best results?

Clean flange faces of carbon, rust, and old gasket material before fitting the new Remflex gasket. Tighten bolts evenly in a crisscross pattern to the manufacturer’s recommended torque so the gasket crushes uniformly and fills any irregularities.

• Prep: remove old gasket residue and grime for a smooth seat
• Torque: tighten bolts evenly to avoid uneven crush
• Inspection: recheck bolt torque after initial heat cycles if desired

Who is this for: The Remflex 8002 is intended for mechanics, DIY enthusiasts, and professional shops that need a durable, heat-resistant exhaust flange gasket for 3" collector joints. It’s a practical choice when dealing with mixed-material flanges (aluminum head to steel header) or any situation where warping or flange irregularities cause leaks, and for anyone who wants a maintenance-minimizing gasket that won’t shrink or harden quickly.
