5/8" Compression Union Fitting

This lead-free brass compression union joins two pipes of the same 5/8-inch outer diameter in compression piping systems. It creates a secure compression bond designed to prevent water leakage. The solid brass construction resists rust and corrosion across commercial and residential applications. The fitting is supplied new and ready for installation.

Practical limits of compression fittings

Compression fittings rely on ferrule deformation to seal, so they require clean, round, and undamaged pipe ends for a reliable joint. Over-tightening can crush the ferrule or split the pipe, while under-tightening leaves a leak path. The lead-free brass body complies with California Proposition 65 warnings for lead exposure, so installers must wash hands after handling. The fitting is not suited for pipes of different diameters or for flared connections.

Installation and common issues

Slide the nut and ferrule onto each pipe, insert the pipes into the union body until they bottom out, then tighten the nuts by hand plus a consistent wrench turn to seat the ferrules evenly. The most frequent problems are leaks caused by debris on the pipe, uneven ferrule seating, or reusing old ferrules that have already been compressed. Always pressure-test the joint before concealing it, and replace any fitting that shows signs of corrosion or cracking.

Questions about this item

Should I pick the 5/8" size or a different diameter for my compression piping?

This fitting is made for 5/8" outside-diameter pipe, so choose it only when both pipes you are joining measure 5/8" OD.

What does the 5/8" O.D. figure mean once the union is installed in a real system?

It means the compression nuts and ferrules will seal onto pipe with a 5/8" outside diameter, creating a watertight joint between two equal-size lines.

What standard does the compression interface follow and what pressure does it cap in practice?

The fitting uses a standard compression-thread design for 5/8" OD tubing; pressure rating depends on the pipe material and installation, not on the fitting alone.
