Fig. 200 Union 2,000 PSI CWP
Recommended for air, water oil or gas service to 2,000 PSI NSCWP. A union of great unity meeting most requirements in the medium pressure seal. Standard subs are threaded for API line pipe. Weco interchangeable 2” available & with butt weld end connections.

Fig. 207 Union 2,000 PSI CWP
Recommended for air, water oil or gas service to 2,000 PSI NSCWP. A blanking cap with Buna-N ‘O’ Ring provides an efficient & dependable closure. The threaded sub is interchangeable with Fig. 200 threaded sub also available with butt weld ends.

Fig. 211 Union 2,000 PSI CWP
Recommended for production systems with electronic corrosion problems Laminated insulating rings provide 35 millions Ohms resistance across the unions. O-Ring in male sub delivers a positive primary seal. Seal ring in female sub delivers a positive secondary seal.

Fig. 400 Union 4,000 PSI CWP
Recommended for air, water, oil, or gas service to 4,000 PSI NSCWP. Utilizes precision ball and cone seating surfaces for easy alignment and dependable pressure seal. Sizes over 4″ are rated to 2,500 PSI NSCWP. Also available with a lip-type seal in 2″ size only as Fig 402.

Fig. 600 Union 6,000 PSI CWP
Recommended for air, oil, gas or steam service to 6,000 PSI NSCWP. Rugged and fast 2 pitch acme thread makes this the quickest unions to makeup or break out (only two turns). The threaded sub is fitted with a bronze seat insert for added effectiveness in pressure sealing.

Fig. 602 Union 6,000 PSI CWP
Recommended for air, water, oil, gas or mud service to 6,000 PSI NSCWP. This unions has a replaceable lip-type seal ring of Buna-N specifically designed to minimize fluid flow turbulence. Lip-type ring provides a pressure seal and protection for metal-tometal seating surfaces. Smaller and lighter than Fig. 600 unions and are recommended for manifold and truck mounting where size and weight are critical.

Fig. 1002 Union 10,000 PSI CWP
Recommended for air, water, oil, gas and mud service to 10,000 PSI NSCWP. This unions has a replaceable lip-type seal ring of Buna-N specifically designed to minimize fluid flow turbulence. The lip-type ring works similarly as in the Fig. 602 unions. These unions are for use on high pressure systems and trucks.

5″ size rated at 7,500 PSI CWP and 11,250 PSI test, 5″ unions for sour gas rated at 5,000 PSI CWP and 7,500 PSI test.

Fig. 1003 Union 10,000 PSI CWP
Recommended for high pressure manifolding and drilling rig use where alignment of piping components is a problem. Recommended for air, water, oil, gas or mud service to 10,000 PSI NSCWP. This unions has a ball seat that allows a total of 15 (±7½ ) angular adjustment. An ‘O’ ring seal in addition to the metal-to-metal seat assures a pressure tight connection.

5″ size rated at 7,500 PSI CWP and 11,250 PSI test, 5″ unions for sour gas rated at 5,000 PSI CWP and 7,500 PSI test.

Fig. 1502 Union 15,000 PSI CWP
Recommended for air, water, oil, gas and mud service to 15,000 PSI NSCWP. This unions has a replaceable lip-type seal ring of Buna-N specifically designed to minimize fluid flow turbulence. The lip-type ring also provides a pressure seal and protection for metal to metal seating surface and are recommended for manifold and truck mounting or other installations where high pressure is encountered.

Derates to 10,000 PSI WP for sour service

Fig. 2002 Union 2,000 PSI CWP
Recommended for standard service to 20,000 PSI NSCWP. Available in butt weld end connections only. Available as Fig 2202 for sour service (15,000 PSI WP).

Fig YH 300 Union 1,000-6,000 PSI CWP
It is a flat face Union with ‘O’- Ring fitted into the groove of the female sub. The ‘O’-Ring is completely enclosed with the flat face of mating part and becomes more effective as additional pressure is
applied.

Fig YH 210 Blanking Union 1,000-6,000 PSI CWP
Recommended for
Mud tanks, mud tank connecting lines, and pump suction flanges

  • Nitrile seal provides a compression seal.
  • Elongated cross-section of seal ring ensures greater sealing surface
    when in contact with the pipe.
  • Accepts up to 7º pipe misalignment.
  • 6, 8, and 10-inch sizes require butt-weld.
