- Connects 1/2" and 3/4" lines with a single brass fitting
- Brass construction resists corrosion in air and water systems
- Compression design seals without solder or special tools
- Legend Valve 303-124 model ensures consistent thread quality
- New condition guarantees unused, factory-fresh performance
Brass Compression Coupling Use
This Legend Valve 303-124 coupling joins a 1/2 inch tube to a 3/4 inch tube using compression fittings. It is built for air compressor and vacuum pump lines where a secure, leak-free joint is required. The brass body resists corrosion in typical workshop environments. Buyers who need a different tube diameter or a threaded connection will not find it here.
California Proposition 65 Notice
The product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm. This notice does not change the mechanical function of the coupling. Installers should follow standard safety practices such as wearing gloves and washing hands after handling.
Installation Practicalities
Slide the compression nut and ferrule onto each tube, insert the tube ends into the coupling body, then tighten the nuts with a wrench until the joint seals. Over-tightening can deform the ferrule and cause leaks, while under-tightening leaves a path for air to escape. Ensure tubes are cut square and deburred before assembly for a reliable seal.

Questions about this item
Will the brass compression coupling need replacement due to dezincification or thread wear over time?
The brass body resists corrosion in typical compressed-air systems; replacement is only needed if the compression nut or ferrule shows visible deformation or leakage during periodic inspection.
What pressure or temperature limit will be reached first during continuous compressor operation?
The coupling is rated for standard shop air pressures and temperatures; the practical limit is the compressor's own cut-out pressure, not the fitting itself.
Does the brass coupling generate heat or vibration noise when the compressor runs all day?
As a passive brass fitting it adds no heat or mechanical noise; any sound or warmth comes from the compressor and piping, not the coupling.
