0708B Thick Gasket for Motive 1108 & 1118 Adapter

The Motive Products 0708B is the thick-profile gasket for the 1108 and 1118 GM brake bleeder adapters. Use the thick variant when the reservoir cap has a deeper recess or you need additional compression to achieve a leak-free seal. Compare with the 0708A (thin) if you're unsure which fits your reservoir — both are inexpensive, so keeping both on hand is common in busy shops.

Specifications

• Fits: Motive 1108 and 1118 GM bleeder adapters

Replace When
