Instrumentation Tube Fittings

Aptek instrument tube fittings are used for leak proof, torque free seal in different instrumentation & process
tubing connections. These products eliminate costly & hazardous leakages.
As shown in the figure the normal tube fitting is made of four parts. The parts are machined as per international standards to achieve the high quality. The frerrules are hardened & burnished for better swaging. The nuts are silver plated for preventing the seize up on the threads. The fitting consists of four parts but when it is fixed to the tube
Materials :-
Aptek fittings are available in different materials as shown in the
below mentioned table.

Compression fittings are rated for working pressure higher than the tubing. Therefore pressure rating depends on choice of tubing which should be based on material. Wall thickness and temperature (see table below). De rating factors must be used to determinate tubing working pressure at high temperatures.
