No Leak Pro Exhaust Flange

Water cooled No Leak PRO flange for 7/8 headers.
Uses two silicone o-rings in a “dry” configuration, meaning that the o-rings are NOT in direct contact with the cooling water.

This flange has the adapter bolted to the head and the flange bolts to that.

Easier to assemble than the standard no-leak flange.

Heavy duty extra thick 6061 T6 aluminum billet
with XL water nipples.

Excellent for use in all gasoline applications, especially big block engines.

Includes exhaust adapter, flange plate, o-rings, water fittings and stainless bolts.

Clear anodized billet aluminum.
