Cautions:
¤ Do not loosen or tighten fittings under pressure.
Anti-Vibration Glａnd Assemblies
The extreme vibration or shock, such as mobile pressure systems or long tubing runs culminating at a compressor that the tubing systems
are subjected to, will be prevented by using FITOK Anti-Vibration Glａnd Assemblies. These assemblies use the same reliable connection
geometries as the standard FITOK fittings, with the added advantage of essentially unlimited vibrational fatigue life.
A coned and threaded tube, when subjected to unusual or excessive vibration, may fail prematurely and break at the last thread. FITOK
Anti-Vibration Glａnd Assembly acts to move the fulcrum of vibration away from the threaded part of the tube and onto the strong, solid
wall of the tubing. A wedge-like collet firmly holds the assembly in place, virtually eliminating premature tubing failure while reliably
maintaining a leakage-free connection between the tube and the connection seat.
20 Series Tubing
¤ Working pressure: 20000 psig (1379 bar).
¤ 316 and 304 stainless steel are standard materials. Other materials are available upon request.
¤ Material, size and heat code are indicated on the tubing surface.
Add the actual foot (feet)/meter (meters) as a suffix to the basic ordering number
to get the complete ordering number.
For example:
1. 10 feet length, O.D. is 3/8", I.D. is 0.203", 316 SS 20 series tube, the complete ordering number is: SS-MT-2FH6-10.
2. 6 meters length, O.D. is 3/4", I.D. is 0.438", 304 SS 20 series tube, the complete ordering number is: S4-MT-2FH12-6M.
