4 to 6 mm Coupler Kit
6mm to 4mm Union w/Barb Coupling Assy.

For connecting EDS inlet port to user supplied 1/8" I.D. soft polypropylene or polyethylene tubing.  This 4 mm to 6 mm union and barbed tube kit allows the 4 mm polyurethane inlet line of an EDS or XCR unit to mate with any soft type 1/8" (3.2 mm) tubing.  The union allows 6 mm polyurethane tubing to be optionally used as the main run from the regulator to the delivery unit.  The union kit is useful in custom system installations or where other primary pressure reducing regulators will be used.

• 4 mm to 6 mm tubing coupler (can be used to replace the 4 mm to 4 mm couple that is usually used on the EDS inlet)
• Blue polyurethane (hard) interconnect tube, 6 mm O.D. x 3 cm long with barb connector for use with user supplied 1/8" I.D. (soft) polypropylene or polyethylene tubing
