Exhaust gaskets built to seal 2.5-inch flanges and resist high temperatures, the YGQ Exhaust Gasket promises a precision fit. Mechanics and home enthusiasts gain confidence from accurate bolt alignment and heavy-duty construction. Is the design the lasting seal needed for demanding silencer jobs?
⚡ At a Glance
- • Seal Performance: Tight seal at 2.5-inch flanges with high heat tolerance and durable compression
- • Best for: Mechanics and DIYers replacing or repairing 2.5-inch, 3-bolt exhaust flanges
- • Not ideal for: Flanges with different bolt patterns or diameters outside the specified measurements
Designed for 2.5-inch, 3-bolt flange connections with precise bolt spacing. Constructed from five-layer galvanised steel with a graphite core and 2.3 mm total thickness.
Consistent leak-free joints, with precise 2.5-inch flange fit and bolt spacing
Centre-to-centre bolt spacing is 77.5 mm, inner-to-inner 66 mm and outer-to-outer 89.5 mm, compatible with bolts under 10.8 mm diameter. The specified dimensions ensure exact alignment for standard 3-bolt 63.5 mm flanges.
Accurate alignment reduces the risk of exhaust leaks and makes installation straightforward on matching flanges.
High-temperature durability, with five-layer galvanised steel and graphite core
A five-layer galvanised steel sandwich surrounds a graphite core, delivering heat resistance and structural integrity. Total thickness measures 2.3 mm for robust compression under thermal stress.
Reliable performance under extreme heat and pressure suits silencer and performance exhaust applications that demand longevity.
Ready spare and tidy storage, with two gaskets packed in a nylon bag
Two identical gaskets are supplied together in a durable nylon storage bag, allowing immediate replacement or a kept spare. Packaging protects parts until fitting.
Having a spare on hand reduces downtime during repairs and keeps components organised between jobs.
