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

Standard Specification:

  • Materials: Aptek fittings are available in different materials as shown in the below mentioned table.
