Legend Valve

Legend Valve 303-105 1" Galvanized Compression Coupling

SKU CH-2X76-PQV27

A 1" galvanized compression coupling for joining pipe or tubing of matching outside diameter

  • 1" galvanized compression coupling fits standard pipe sizes
  • Galvanized coating resists corrosion for longer service life
  • Compression design seals without threading or soldering
  • Legend Valve brand trusted in plumbing and air systems
  • California Proposition 65 warning: contains chemicals known to cause cancer and reproductive harm

Application & Suitability

The Legend Valve 303-105 is a 1" galvanized compression coupling designed for joining pipes in air compressor and vacuum pump systems. It serves installers and maintenance teams who need a reliable mechanical connection without threading or welding. The galvanized finish provides corrosion resistance for standard compressed air and vacuum service. Buyers requiring different pipe diameters, non-galvanized materials, or specialized chemical compatibility should look elsewhere.

Capacity & Limits

This coupling accommodates 1" outside diameter piping using a compression fitting method that seals through ferrule deformation. The galvanized steel construction handles typical shop air pressures and vacuum levels encountered in automotive and industrial power tool applications. It is not rated for hydraulic pressures, extreme temperature cycling, or media incompatible with zinc-coated steel. California Proposition 65 warnings indicate the presence of chemicals known to cause cancer and reproductive harm.

Installation Context

The compression design allows assembly with standard wrenches, eliminating the need for pipe threading equipment or soldering tools. It fits directly into existing 1" OD piping runs, freeing installers from alignment constraints imposed by rigid threaded joints. The coupling ships directly from the manufacturer, and orders of $75 or more qualify for free shipping. No additional seals, gaskets, or proprietary tools are required for a standard installation.

Questions about this item

Will the 1" galvanized compression coupling join to the existing 1" galvanized pipe in my shop air line?

Yes, the coupling is sized for 1" galvanized pipe and uses a compression (OD) joint that seals on the pipe's outside diameter without threading.

How can I verify the joint is leak-free after I tighten the compression nuts?

Pressurise the system to working pressure and brush soapy water over both nuts; bubbles indicate a leak, while a dry surface confirms a sound seal.

Does the box include the compression nuts and ferrules, or must I buy them separately?

The coupling ships as a complete assembly with both compression nuts and ferrules already captured, so no extra parts are required for installation.
