Thread

Our whole line of threaded items, including sealing collars, are guaranteed to be produced with no seams.

Connectors of series 1-3 are produced with both male and female thread with the thread length of the male threads meeting the requirements of the applicable standards. Our standard connectors are available with BSP(G), NPT, Metric(M) and UNF threads.

Cylindrical Thread: G, M or UNF

For optimum assembly of a connector, tightening must be limited by a defined stop. Our G, M and UNF threads provide this option. Sealing is ensured by the sealing collar. In special cases the sealing can be supplemented by an O-ring.

Conical thread: NPT

The seal of the NPT thread is provided in the thread itself rather than by a sealing collar.

Dead volume free connection

In order to exclude unwanted dead volume, emtechnik has developed a type of screw connection with a cylindrical G thread that seals via a cone (outer cone). The prerequisite is that the internal thread also has the same cone (internal cone).

Please note: Generally speaking, however, each type of thread should only ever be connected with the same type of thread. For example if you are using a male connector with a male G-thread, the mating part should always have a female G-thread. The conical male thread in a cylindrical female thread shown in the drawing clearly illustrates that it is not possible in this case to produce a tight-fitting and therefore tight connection.
