FAQs
What size hydraulic pipe do these fittings fit?
These fittings are designed to fit 3/16" hydraulic brake pipes.
What is the thread size of these fittings?
The thread size is 5/8" x 18 UNF.
Can I use these fittings with steel brake lines?
These fittings are designed for flexible hydraulic brake pipes (copper or copper-nickel), not for direct connection to rigid steel brake lines which typically use different fitting types.
What materials are the fittings made from?
They are manufactured from steel and are zinc-plated for corrosion resistance.
How many fittings are included in this pack?
This pack contains 20 fittings: 10 male and 10 female.
Are these fittings suitable for all types of brake pipes?
They are suitable for copper and copper-nickel brake pipes, but only those with a 3/16" diameter and requiring a 5/8" x 18 UNF connection.
Do I need a special tool to install these?
Yes, you will need a flaring tool capable of creating a 5/8" x 18 UNF flare on the 3/16" brake pipe for proper installation.
Troubleshooting
Fitting will not thread onto brake pipe.
Ensure you are using a 3/16" brake pipe and have correctly flared the end with a 5/8" x 18 UNF flaring tool. Check for any burrs or damage on the pipe end or inside the fitting.
Leak after installation.
The brake pipe may not be correctly flared, or the fitting may not be sufficiently tightened. Re-check the flare integrity and tighten the fitting slightly. Ensure compatibility with the mating part.
Fitting feels loose on the pipe.
The brake pipe may be slightly larger than 3/16" or the flare is not tight. Ensure you are using the correct pipe size and that the flare is properly formed and seated within the fitting.
Corrosion on the fitting.
While zinc-plated, prolonged exposure to harsh chemicals or extreme moisture can cause corrosion. Clean gently and consider applying a protective lubricant suitable for brake components if further protection is needed.
Pros and Cons
Pros
- Made from strong and durable steel.
- Zinc plating provides excellent rust and corrosion resistance.
- Includes both male and female fittings for versatile use.
- Designed for 3/16" brake pipes, ensuring a secure fit.
- Suitable for use with both copper and copper-nickel brake pipes.
Cons
- Strictly compatible with 3/16" brake pipes; not suitable for other sizes.
- Requires specific 5/8" x 18 UNF flaring tools for proper installation.
- Not intended for use with rigid steel brake lines directly, requires hydraulic pipe.
- Only available in one specific thread size and pipe diameter.
Setup, Compatibility & Care
Setup: These fittings are designed to be used with brake pipes that have been correctly flared using a 5/8" x 18 UNF flaring tool to create a double lap flare or similar standard. Ensure the pipe is clean and free of burrs before attempting to fit the connector. Thread the fitting onto the pre-flared pipe, ensuring it starts easily to avoid cross-threading. Tighten securely using appropriate wrenches, but avoid over-tightening which could damage the flare or fitting.
Compatibility: These fittings are specifically compatible with 3/16" diameter hydraulic brake pipes made from copper or copper-nickel alloys. The thread size is 5/8" x 18 UNF. They are designed for use within automotive hydraulic brake systems. Ensure your existing brake system components (e.g., master cylinder, brake calipers, wheel cylinders) have the corresponding 5/8" x 18 UNF male ports or that you are connecting to another 5/8" x 18 UNF male fitting.
Care: Due to the zinc plating, these fittings are protected against corrosion. However, it is advisable to store them in a dry place away from moisture. If they become dirty during installation, clean with a dry cloth. Avoid harsh cleaning chemicals which could damage the plating.
