Tapered Pipe Fittings

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 Thread Fittings

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:

  • Rubber-on-metal seating does not distort any metal parts
  • Provide a tangible “feel” when the connection is tight.
  • Virtually unlimited disassemblies and reassemblies, though the o-ring should always be replaced as a precaution. Variety of compounds available for compatibility with system and environmental media.
  • Adjustable and non-adjustable. adjustable fittings, such as elbows and tees, allow the user to orient the shape in the desired direction before tightening to assemble.
