EDM Tube Fitting is designed using industrial codes and specifications with additional Cutting-Edge Engineering on swaging action and sealing integrity. EDM provides excellent leak-free sealing on high pressure gas, vacuum, impulse, thermal shock, heavy vibration, and many other stringent applications.

EDM Tube Fitting consists of body, front ferrule, back ferrule and nut. The features include.
■Excellent product range up to 2 in. and 38 mm O.D..
■Additional engineering on sealing integrity.
■Swaging action.
■Re-usable and predictable quality.
■Excellent leak-free sealing integrity on heavy vibration, vacuum and impulse.
■Heat-Code Traceability.
■No torque transferring to connective tubing during installation.

Metric EDM tube fitting has stepped shoulder on body and nut hex. Shaped fitting such as tee, elbow, and cross forging has no such step on body.

■EDM Tube fittings are supplied assembled and finger tight. Disassembly before use can allow the entry of dirt or other particles.
■Insert the tubing into the EDM Tube fitting. Check that the tube rests firmly on the fitting shoulder and that the nut is finger tight. At this point it is recommended that a scribe mark be drawn on the hex of the nut extending onto the fitting body. This mark will serve as an indicator for the starting point and proper pull-up.
■Tighten the nut.
■1-1/4 turns of the nut are required for 1/4” (6 mm) and higher (see Fig. 1). 3/4 turn of the nut is required for 3/16”(4 mm) and lower (see Fig. 2).

■Reinstallation (all sizes).
■Mark on the nut and body before disassembling the fitting.
■Tighten the nut to the marked location before reinstallation.
■Tighten the nut slightly with wrench.

■Do not loosen or tighten fittings when system is pressurized.
■Make sure that the tubing rests firmly on the shoulder of the port.
■Always leave enough straight length of the tubing for the fittings.
■Always use an insert for extremely soft plastic tubing.
■Material of the metal tubing should be softer than that of the fitting. For example, stainless steel tubing should not be used with brass fittings. When tubing and fittings are made of the same material, the tubing must be fully annealed.
■The allowable working pressure of the tube fitting is rated to the maximum working pressure of the corresponding tubing, which can be found in tubing data sheet. For those which can not be found in tubing data sheet, please contact the authorized representative for related information.
■Keep the tubing end and surface clean and smooth.
■Always use proper thread sealants on tapered pipe threads. Make sure that its working temperature does not exceed that of the sealants.
■When assemble the tube fitting, hold the body with a wrench and turn the nut instead of holding the nut.
■When install a valve with tube fitting end, hold the valve body with a wrench and turn the nut.
■When assemble the fitting to a valve with thread, hold the valve body with a wrench and turn the body of the fitting.
