The washer, made in stainless steel, ensures the perfect tube clamping with every kinds of materials without damage the surface.
The connection between the tube and the fitting ensures a total tightness even in severe conditions such as impact and vibrations.
The particular geometric shape of the seal ensures the perfect tightness even with vacuum.

All of threads from this range (also the M5), have been equipped with tightening parts which allow the direct assembly of the fittings, reducing the installation time.

All the straight fittings, with “short” and parallel threads, can be assembled with Allen wrench and it is possible to use them in reduced spaces.
The “short” taper thread has been designed to offer the following advantages to the users:
– reduced overall lenght
– smaller hex dimension compared to the parallel threads
– to allow the assembly with different female threads both taper as well as parallel:         – tapered NPT – NPTF
         – parallel ISO 7 – BSPP
         – tapered ISO 7 – BSPT – PT
         – parallel ISO 228 – BSP – PF
– to ensure the right tightening also with surfaces not perfectly flat, without spot-facing, concave, convex and with different kinds of chamfers or radius.
