Precision Engineering for Your Go Kart Engine For Sale

Whether you are bolting up a brand new go kart engine for sale or dialing in your existing hydraulic brake system, the MCP 68A-3A Brass Compression Fitting with Ferrule is an absolute necessity. This isn't just a generic piece of hardware; it is a purpose-built, vibration-resistant connector designed to handle the extreme pressures of competitive racing. By utilizing a crush-style brass ferrule, this fitting creates an impenetrable seal around standard 3/16" nylon brake and throttle lines, ensuring zero fluid leaks and zero cable slippage when you dive into the apex.

Frequently Asked Questions

Q: How do I properly install this compression fitting?

A: Slide the nut and then the brass ferrule onto your 3/16" nylon line. Insert the line fully into the fitting body, then tighten the nut by hand until snug. Use a wrench to tighten an additional 1/2 to 3/4 turn to compress the ferrule and create a leak-proof seal. Do not overtighten, as this can crush the nylon line.

Q: Is this fitting compatible with steel braided lines?

A: No, this specific compression fitting is designed exclusively for 3/16" nylon tubing. For steel braided lines, we recommend using AN-style fittings to ensure proper sealing and safety.

Q: Can I reuse the brass ferrule if I disconnect the line?

A: It is highly recommended to replace the ferrule whenever the line is disconnected. Because the ferrule works by deforming (crushing) to create a seal, it will not provide a reliable, leak-free connection if reused.

Q: What does the 1/8" NPT designation mean?

A: 1/8" NPT refers to the National Pipe Taper thread size. This is the standard thread pattern used on most MCP master cylinders and calipers, ensuring a secure, pressure-tight fit when threaded into your brake components.
