Connections of tapered threads pipe fittings:

Tapered (“Pipe”) Threads

There are three types of tapered threads commonly used in industrial applications.

NPT/NPTF

BSPT

Metric Taper

All three thread styles noted above use the same basic metal-to-metal sealing design for achieving a seal. Although very similar, there are differences in the thread dimensions, pitch, and flank angle that do not allow interchangeability.

 

Connections of Parallel Thread Hydraulic  Pipe Adapters:

Straight parallel thread ports in various forms are becoming more popular in hydraulic systems because they are more reliable and easier to service.

Three types of threads are used for parallel thread ports:

UN/UNF (SAE straight thread) SAE J1926 ORB or O-ring boss in North America.

BSPP (British Standard Pipe, Parallel) In Europe, Japan etc, sealing method of an O-ring

and retaining ring; cutting face or an EOlastic seal.

Metric parallel O-ring and retaining ring seal;  a cutting face or an EOlastic seal; o-ring seal.

Because parallel threads only serve one function (i.e. holding the fitting in place), some other means of sealing is always present, such as an elastomeric O-ring or a metal seal.

 

We can offer hydraulic pipe fittings and port adapters such as: nipples, couplings, reducers, expanders, conversions, shape types 45 degree elbow, 90 degree elbow, tees, cross, plugs, bleed adapters.
