Parker Triple-Lok® 2 Soft Seal 37° Flare Tube Fittings

Parker Triple-Lok 2 37° flare tube fittings utilize an elastomeric seal (O-ring) in the flare nose for improved seal reliability in applications where stainless steel fittings are required.

Similar to the standard stainless steel Triple-Lok fitting, Triple-Lok 2 consists of three pieces: the body (with O-ring), the standard Triple-Lok sleeve and standard Triple-Lok nut. The tube end is flared at a 37° angle (74° included angle) and held between the fitting nose and sleeve with the nut, providing a very effective elastomeric seal between the fitting nose and the tube flare.
