Stainless steel threaded fittings are indispensable connecting elements in piping systems.

Important information on technical changes, applications, standards and guidelines

Stainless steel threaded Fittings

Threaded Fittings are divided into two main groups:

 

  • Standard fittings such as nipples, sockets, reducers, plugs, caps, nuts, screw plugs, hose nipples, elbows, T-pieces, cross-pieces and B&O fittings

 

  • Fittings, interchangeable three-part fittings in straight, angled or T-design.

 

The fittings can be either conical sealing or flat sealing (standard: PTFE seal; other seals such as EPDM or Klingersil on request).

The threads comply with international standards, including:

 

  • DIN EN 10226-1 (ISO 7-1): Tapered Whitworth pipe thread for thread-sealing connections

 

  • DIN EN ISO 228-1: Cylindrical Whitworth pipe thread for non-thread-sealing connections

 

  • NPT (ASME/ANSI B1.20.1): American conical pipe thread for self-sealing fittings.

The threaded fittings are divided into the following types: nipples, couplings, reducers, plugs, caps, nuts, screw plugs, hose nipples, elbows, tees, crosses and arches. The interchangeable tube fittings according to DIN 2993 are divided into Straight, angle and T-fittings. They have conical or flat seals (flat seals PTFE, other types of seals on request).

The different types of threads (eg tapered Whitworth pipe thread to DIN 2999, cylindrical Whitworth pipe threads according to DIN ISO 228, NPT) and connection types (eg, pipe, hose connection, Welding end) round of the range. Furthermore, different qualities and materials are available (eg material no. 1.4571, 1.4408, 1.4404, 1.4301).
