4 Unions are available with line pipe ortubing threads, butt-weld, or nonpressure-thread seal end sealing designsWeco wing union seals vary according topressure and application. All wing unionsprovide positive, pressure-tight low-pressure services (1,000 to 2,000psi), the spherical surface of the male sub andthe conical surface of the female sub form ametal-to-metal seal. This ball-and-cone sealremains leak-proof even when one surface isslightly pitted or medium-pressure models (2,000 to4,000 psi) supplement the metal-to-metal sealwith a resilient O-ring in the male 1502 ..5 Figure 2002 ..5 Figure 2202 ..6 Sour Gas Service ..6 Nonpressure-Thread Seal Connection ..6 Tank Unions ..7 Air-o- Unions ..7 Suction-Hose Unions .

5 7 Specifications ..8 Warnings and Safety Instructions .. 12 Weco high-pressure Unions (6,000 to20,000 psi) feature a replaceable, lip-typeseal ring in the female sub. This primaryseal protects the secondary metal-to-metalseal from abrasion and corrosion whileminimizing flow Weco nonpressure-thread sealoption is designed for abrasive, high-pressure applications where weldedconnections are undesirable. (Details onthis design can be found on page 6.)Fast make-up and break-outThree-lug nuts and rugged self-lockingACME threads provide fast make-up andbreak-out regardless of position or spacerestrictions. No special tools are identificationWeco standard service wing Unions arecolor coded for quick identification. Sourgas wing Unions are stamped sour gas using low-stress dot stamping and paintedwith a green, zinc-chromate primer unique tosour gas you should standardize withWeco Original Wing UnionsInterchangeable partsAll Weco parts of the same size, pressurerating, and figure number are feature makes it easy to match male andfemale subs that are frequently made-up andbroken-out.

6 And, because FMC makes everyWeco wing union to the same rigid standards,you get a quick and positive seal every quality controlWeco Unions are produced using thefinest raw materials, tooling procedures, andheat-treating techniques available. Each unionis carefully inspected to assure long, depend-able service in the most extreme wing Unions , like all pressurecontaining equipment, require special care anduse.
