What are the Benefits of a Steel Male Coupler?
The steel male coupler is made of a stainless steel material that helps prevent corrosion. It is interchangeable with different types of standard series couplings, including industrial pipe size couplings, interchange type couplings, and 1/2″ Hose Connection Couplings.
The coupler is compatible with A-style and M-style plugs and can sustain a temperature of up to 250 degrees Fahrenheit. With a push-type sleeve release, the steel male coupler maintains airflow of 74 SCF/minute. This coupler is highly versatile and often recommended for any type of percussion tool application.
