Earls Quick Disconnect Clutch Adapter Fitting Male -4AN 90 Degree
Earl's Performance clutch adapter fittings convert OEM master cylinders, clutch release bearings, and slave cylinders to accept a better replacement for your less-than-perfect OEM plastic hose. These quick-disconnect fittings work perfectly with Earl's Speed Flex hose (not included). They're made from 304 stainless steel or aluminum and include EPDM O-rings. The adapter fittings are offered in several early and late model vehicle styles, straight and 90 degree angle. Check your OEM hose for the proper fit.
