Inlet Adapter Compact Remote Master Cyl.

The Wilwood Inlet Adapter Compact Remote Master Cyl. (part 260-10264) is the replacement reservoir inlet fitting for Wilwood compact remote master cylinders. It threads into the master cylinder body and accepts the feed line from a remote brake fluid reservoir, restoring a clean, leak-free connection during a rebuild or a fresh plumbing job. Builders running pedal assemblies and remote-mounted reservoirs reach for this small part when an original adapter cracks, strips, or goes missing. It is a direct-fit component for Wilwood's compact remote master cylinder family, not a universal substitute, so it drops into an existing setup without modification.

Wilwood molds this adapter from high-strength black plastic, which holds up to brake fluid exposure and keeps weight down to about 0.02 lbs per the datasheet. The inlet uses a 1/4 in. hose barb that grips a standard remote reservoir feed line, while the threaded end mates to the compact master cylinder port. That barb-to-thread design lets you route a flexible line from a reservoir mounted away from the master cylinder, which matters in tight chassis where there's no room for a top-mounted tank. Because it ships as a single fitting, it pairs naturally with a fresh feed line and a matching reservoir. If you're refreshing the whole circuit, look at our remote reservoir options and master cylinder covers at the same time.

Most buyers grab this adapter mid-build or mid-repair: swapping a master cylinder, plumbing a remote reservoir on a race chassis, or replacing a fitting that failed during a fluid flush. Keep one on the shelf if you run Wilwood compact remote master cylinders, since the plastic fitting is the part most likely to need attention over time. When you're sourcing the rest of the circuit, our full brake parts catalog covers master cylinders, reservoirs, and the smaller fittings that tie a hydraulic system together, including the remote reservoir inlet fitting for related Wilwood setups.
