SSP offers a wide selection of tapered and straight thread pipe fittings and adapters for industrial applications.
Tapered Pipe Fittings are still widely used in industry. That is because of their relative low-cost, widespread familiarization among users, lack of alternative port designs offered by many component manufacturers, and/or when exposed to more caustic media which requires the corrosion resistance of metal-only seals.
Straight threaded fittings and adapters (also known as o-ring boss fittings and BSPP fittings) seat an o-ring on the shoulder of the male half of the connector against a metal sealing surface on the female port. Sealing is achieved and maintained by o-ring compression resulting from the clamping force generated by the tightening action. The straight threads do not seal; they provide the resistance (holding power) for service pressure.
Straight thread adapters feature:
