Acetylene Adapter - B-Tank Cylinder to MC-Regulator

Connect Your MC Regulator to a B-Tank

Every welder and HVAC technician knows the frustration of having a perfectly good regulator that just won't fit the tank available at the job site. The Western Enterprises 306 Adapter is the problem-solver you need in your kit. If you typically run a portable "MC" acetylene setup (the small 10 cu. ft. tanks) but find yourself needing the longer run-time of a "B" tank (40 cu. ft.), this adapter bridges the gap. It converts the B-tank's valve to fit your MC regulator, saving you the cost of buying a second regulator.

Built for Safety and Durability

When dealing with acetylene, safety is paramount. This adapter is machined from solid brass, a non-sparking material that stands up to the rigors of field work. It is rated for 500 PSIG, which is well above the standard working pressure of acetylene cylinders. The 1-1/8" hex design gives you plenty of surface area to get a wrench on it, ensuring you can tighten it down securely to prevent dangerous leaks. It's a small part, but it's built with the same quality as your heavy-duty torches.

Practical Application

This adapter is particularly useful for plumbers and HVAC pros who might switch between light repair work and larger installation jobs. Instead of hauling different regulators for every tank size, you can standardize on your preferred MC regulator and use the WES306 when you need to hook up to a larger supply. Just screw the adapter into the recessed valve of the B-tank, and then attach your regulator to the male threads of the adapter.

Note: Always remember that adapters are designed for temporary connections. When you are done with your work, break down the setup and store the adapter safely. Do not leave it permanently installed on the cylinder. Always perform a quick leak check with a soapy solution after connecting to ensure gas-tight integrity before lighting your torch.
