Features Technical information • DK-Lok weld tube socket ports have a tapered sizing angle at the end that holds tubing properly and provides approx. This feature allows consistent welding assembly as well as pre-assembly of many tubing runs before welding. • Fittings are available in stainless steel only. Thus the part number of table below contains the material designator-S. the same corrosion resistance. Pressure ratings shown in the dimensional tables are calculated in accordance with the requirements of ASME B31.3 Tapered sizing angle provides approx. 1.5mm gap Part Number T Tube O.D d mm D mm E mm L mm Working psig Pressure bar 1/4 4.6 13.0 7.1 19.0 10,000 689 3/8 7.1 15.8 7.9 22.4 7,600 523 1/2 10.2 19.0 9.7 26.9 6,200 427 5/8 12.7 24.0 10.4 30.2 6,400 440 3/4 15.7 26.9 11.2 33.3 5,500 378 1 22.1 35.0 15.7 36.6 5,200 358 Part Number T Tube O.D d mm D mm E mm H Wrench Flat mm L mm Working psig Pressure bar 1/4 4.6 13.4 7.1 12.7 21.8 11,300 778 3/8 7.1 15.8 7.9 12.7 24.5 8,400 578 1/2 10.2 20.6 9.7 17.4 29.0 7,800 537 5/8 12.7 23.8 10.4 20.6 34.5 6,700 461 3/4 15.7 28.6 11.2 25.4 37.0 6,700 461 1 22.1 35.0 15.7 31.8 46.5 5,800 400 Part Number T Tube O.D d mm D mm E mm H Wrench Flat mm L mm Working psig Pressure bar 1/8 2.3 13.4 2.5 12.7 15.0 11,800 813 1/4 4.6 13.4 7.1 12.7 21.8 11,300 778 3/8 7.1 15.8 7.9 12.7 24.0 8,400 578 1/2 10.2 20.6 9.7 17.4 29.0 7,800 537 5/8 12.7 23.8 10.4 20.6 34.5 6,700 461 3/4 15.7 28.6 11.2 25.4 37.0 6,700 461 1 22.1 35.0 15.7 31.8 46.5 5,800 400 Part Number T Tube O.D P NPT in. d mm D mm E mm H Hex mm L mm Working psig Pressure bar 1/4 1/4 4.6 12.2 7.1 14.2 29.2 7,500 516 3/8 1/4 7.1 15.3 7.9 15.8 31.8 7,500 516 3/8 3/8 7.1 15.3 7.9 17.4 31.8 7,300 502 3/8 1/2 7.1 15.3 7.9 22.2 37.8 7,200 496 1/2 1/4 7.1 18.5 9.7 19.05 33.3 6,200 427 1/2 3/8 9.4 18.5 9.7 19.05 33.3 6,200 427 1/2 1/2 10.2 18.5 9.7 22.2 38.9 6,200 427 UNION GUSW Tube to Tube UNION TEE GTSW Tubes UNION ELBOW GLSW Tube to Tube MALE CONNECTOR GCMSW DK-GUSW- 4T-S-.
