Addaptor for R410a & R32 straight 90433 with BALL VALVE MASTERCOOL USA 

The straight addaptor 90433, with 1/4FL.M x 5/16FL.F threads easily connects to any transfer hose and converts it to R410a or R32 compatible. Reliable operation with built-in ball valve, prevents the loss of expensive refrigerant and protects the environment.

Mastercool is one of the leading manufacturers of professional quality "auxiliary accessories" in the American continent.

It manufactures a complete line of shut-off valves for refrigerant limitation, so the adapters are made of the best materials and precision machined according to the highest quality standards, meeting the requirements of the American EPA which requires shut-off valves within 30cm of the ends of the transfer pipe to avoid unnecessary refrigerant venting. Using shut-off valves is much safer than letting the refrigerant escape during service. For flexibility, Mastercool offers rotating ball valves individually, without the pipes, so they can also be used in recycling equipment, flushing, pressure gauge housings, etc.

At Mastercool, every tool we build is designed to last for many years of hard use!
