¤ Anti-vibration connection components available.
¤ Fittings are easy to disconnect and retighten.
¤ Material is high tensile 316 stainless steel.
¤ Every fitting is stamped with size, material and heat code.
Working Pressure
¤ Working pressures for 60 series tube end connections used in this catalog are identified below.
Data in this table is applied only to the working temperature below 800°
above 800°F (427° C), please consult FITOK Group, then we will provide you relative solutions.
Working Temperature
¤ Temperature Rating: -423°F (-252°C) to 1200°F (649°C).
Installation Instructions
¤ Refer to the Tools andIn stallation Instructions.
Cautions:
¤ Do not loosen or tighten fittings under pressure.
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
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.
60 Series Tubing
¤ Working pressure: 60000 psig (4137 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 1/4", I.D. is 0.083", 316 SS 60 series tube, the ordering number is: SS-HT- 6 FH4-10.
2. 3 meters length, O.D. is 9/16", I.D. is 0.188", 304 SS 60 series tube, the complete
ordering number is: S4-HT-6FH9-3M.
