Quick Couplings"O" Seal unions are recommended where pipingrequirements dictate the necessity of having a flat faceseat to make and break the pipe line. They meet requirementswhere an O-ring, zero leakage, seal isrecommended.Features■■■■■■■■■Turbulance-free fit across seats. Full bore I.D.O-ring located in the threadpiece face, well out of the waterwaybore providing added protection against abrasives anderosion.Combination end connections. Threaded, socketweld andbuttweld ends are all interchangeable, as well a one-step linesize changes.3,000 psi W.O.G. Cold non-shock pressure rating is standard.6,000 and 9,000 psi are also available.Precision machined parts. Ends taper reamed before threading.Resistance to vibration. Seals will not loosen, even underextreme vibration or pressure surges.No maintenance needed because once the seal is made itnever requires retightening.Saves money and weight by eliminating unnecessary nipples,brushings, couplings and inserts when initially designed intothe system.Flat faced construction allows for slipping the component inand out without disturbing the surrounding tube or pipe sections.Design StandardsUnions are designed to comply with current industrystandards for pressure piping. These standardsinclude ANSI B 31.1 "Power Piping", ANSI B16.11 "Forged Steel Fittings Socket Welded andThreaded", and ASME "Boiler and Pressure VesselCode".O-ring assurespositive sealingHammer Blow-Lug NutFor fast make and break■■■■Designed for rough treatmentNo special tools neededFits all "O-Seal" unionsSpecify prefix letter "H"Orifice UnionFor precise regulation of flow andpredetermined pressure drop■■■■Double O-ring design for zero leakageIf pre-drilled, specify orifice hole diameterdesired (minimum drilling: 1/64").
