The 250-B-FSP o-ring is compatible with Filter Specialists, Inc. (FSI) FSPN 250 industrial bag filter housings. This o-ring ensures a tight, leak-proof seal between the filter vessel body and the lid assembly. The 250-B-FSP o-ring measures approximately 15-1/2” diameter.
Inspect the o-ring upon filter bag change to check for signs of wear, flattening, cracking, or swelling. Replace your o-ring to restore a tight, teak-proof seal. The correct o-ring ensures proper seating of the filter bag to prevent bypass.
Molded from Buna-N (Shore A 70 durometer, also called Buna Nitrile, Nitrile Butadiene, or NBR70) rubber, for service temperatures of -40F (-40C) to 250F (121C). This o-ring is fully molded (not cut from cord and spliced like inferior o-rings).
