Welcome to contact IFAN, we are online 24 hours a day to answer your questions!

Main Components and Structure

Each brass compression fitting includes a body, nut, and compression ring (ferrule).
The brass body withstands high pressure and temperature fluctuations in plumbing lines.
Ferrules often come in brass or plastic depending on pipe material.
Markings on the body indicate size, pressure ratings, and threading details.

Installation Method and Key Steps

Cut the pipe cleanly and square using a proper pipe cutter.
Slide the nut and ferrule onto the pipe in the correct order.
Insert the pipe into the fitting body until it stops.
Tighten the nut by hand, then finish with a wrench without over-tightening.
Test the connection with pressure to confirm no leakage exists.

Common Applications and Sizing

Brass compression fittings come in sizes from 1/4 inch to 1 inch and above.
Plumbers use them in sinks, toilets, water heaters, and control valves.
The fittings suit both potable water and low-pressure gas systems.
Some versions include integrated shut-off valves for added functionality.

Handling and Safety Tips

Use Teflon tape only on threaded versions when required by specifications.
Avoid reusing compression rings, which may deform after one use.
Do not overtighten, as this can crack the pipe or deform the ferrule.
Store fittings in dry areas to prevent corrosion before installation.
Follow all plumbing code requirements when selecting and installing these fittings.
