Western Enterprises Hose Couplings provide a secure, leak-free way to join two welding hoses end-to-end. Built from precision-machined brass and threaded to the industry-standard B fitting (9/16″–18), these couplings deliver reliable performance in oxy-fuel cutting and welding setups.

Choose the correct thread for your gas service: Oxygen (#30, RH thread) or Fuel Gas (#31, LH thread). Using the proper handed thread helps prevent cross-connection and keeps your system safe.
