Drain Cocks

Steam operated

My drain cocks are made from brass and have an "O" ring seat and an "O" ring on the steam piston. They are available with 3/16" x 40tpi, 1/4" x 40tpi, 5/16" x 26tpi and 3/8" x 26tpi mounting threads. Special mounting threads can be fitted on request.

My steam operated drain cocks require a three way valve to open and close the drain cocks. These are listed below.

 A set of 4 drain cocks (2 left hand, two right hand) sell for:

   - $80 plus postage for 3/16" and 1/4" sizes

- $100 plus postage for 5/16" and 3/8" sizes
