Military “Y” Strainers (Staples & Pfeiffer)

Y-strainers are used to remove solids from liquid, gas, or steam applications in small volumes.  Y-strainers can be fitted with a blow off connection on the cover, to permit cleaning the screen without removing the cover.  Staples & Pfeiffer Y-strainers are offered in 150# and 250# class.  Y-strainers can be provided in either ASTM B61 or  ASTM C958 bronze.  Strainers have been shock tested to MIL-S-901D and are fabricated to meet or exceed Mil-S-16293.

STAPLES & PFEIFFER, INC was established in 1900 by Lyman Staples and August Pfeiffer and originally located in San Francisco, California.
