2" CTS Brass Compression Coupling
This Legend Valve coupling joins two 2" CTS pipes using a compression fitting made of brass. It is intended for plumbers and maintenance teams who need a reliable joint on copper tube size lines without soldering or threading.
Compression fitting limits
Compression fittings seal by ferrule deformation rather than thread engagement, so they must be tightened to the manufacturer's torque specification to prevent leaks. Over-tightening can crush the ferrule or distort the pipe, while under-tightening leaves a path for fluid escape. The brass body resists corrosion but is not rated for extreme pressure spikes beyond the pipe class.
Installation notes
Slip the nut and ferrule onto each pipe end, insert the pipe fully into the coupling body, then tighten the nuts evenly with two wrenches to avoid twisting the pipe. Common errors include reusing old ferrules, failing to deburr the cut pipe, and mixing metric and CTS sizes which have different outside diameters.

Questions about this item
What does the 303-129 model number identify for this Legend Valve coupling?
The 303-129 model identifies a 2-inch CTS brass compression coupling designed for joining copper tube size piping in plumbing systems.
How does the 2-inch CTS sizing translate when installed on copper tubing?
The coupling fits 2-inch copper tube size pipe by outside diameter, creating a watertight seal when the compression nuts are tightened onto the tubing.
What does the compression connection method limit compared to soldered joints?
Compression fittings allow disassembly for maintenance but require periodic re-tightening, unlike permanent soldered connections.
