Medium Pressure Tube Fittings 20D Series
Medium Pressure Tube Fittings, 20D Series
20D Series Medium Pressure Double Ferrule Tube Fittings feature a front and rear ferrule design for easy assembly, disassembly, and reassembly. They withstand high temperatures and pressures, remain unaffected by pressure and temperature cycles, and prevent leaks caused by vibrations, even in extreme working conditions. The working pressure of the tube ends at ambient temperature is determined by the working pressure of the tubing used, which is up to 20,000 psig (1379 bar). These fittings are EC-79 certified and suitable for 70 MPa vehicle hydrogen systems. Available in various sizes and types, they deliver optimal performance when paired with FITOK T20D series tubing.

20D Series Tube Fittings
Working Pressure
- Working prorking pressure is determined by the lowest assure of the ends
Tube Ends - The working pressure of tube ends at ambient temperature is determined by the working pressure of the T15 and T20D Series tubing used. For details, please refer to “Working Pressure at Ambient Temperature”on B-06 and B-09.CAUTION: 20D Series Tube Fittings are not applicable for use with T20M Series Tubing.
Working Temperature
- The ends are supplied with a fluorocarbon FKM O-ring as standardother materials of O-rings available.
60 Series High Pressure Fittings
- Always use proper thread sealants on tapered pipe threads
- The data are based on the working temperature range of the thread sealants. For the working temperature above 400 (204 ).
