Product identity
The Legend Valve 303-129NL is a 2" CTS brass compression coupling designed for air compressor and vacuum pump installations. It joins two copper tube size pipes of matching diameter in plumbing and pneumatic systems.
Sustained load behaviour
Brass construction resists corrosion and handles continuous pressure cycles typical of compressed air lines. The compression design maintains a reliable seal under vibration and temperature variation without soldering.
Installation reality
Slide the nut and ferrule onto each pipe end, insert into the body, and tighten the nuts to compress the ferrules. Over-tightening can deform the ferrule and cause leaks, while debris on the pipe surface prevents a proper seal. California Proposition 65 warnings apply to this product.

Questions about this item
Does the 2" CTS brass compression coupling generate any noise, heat or power draw when installed in a line?
The coupling is a passive brass fitting with no moving parts, so it produces no noise, no heat and draws no power during continuous operation.
What pipe or tubing must I already have for this 2" CTS compression coupling to seal properly?
You need 2" CTS (copper tube size) tubing or pipe with the correct outside diameter for the compression ends to grip and seal.
Will this lead-free brass coupling work alongside older non-lead-free brass fittings in the same system?
Yes, the 2" CTS compression ends connect mechanically, so the coupling can join directly to existing brass fittings regardless of their lead content.
