Cold working pressure - 2,000 psi (138 bar)
'Flat Face' design facilitates straight breakout of connected components such as valve or fittings for repair or inspection.
Moderate vacuum service insulating unions available on special order.

Figure 400
Cold working pressure - 4,000 psi (276 bar) 2" through 4" sizes, for 5" to 12" sizes, cold working pressure is 2,500 psi (172 bar).
Mainly used for manifold pumping and mud.

Figure 600
Cold working pressure - 6,000 psi (414 bar).
Used for steam service, well servicing and boiler connection.
Primary seal is bronze to prevent corrosion and absorb expansion and contraction.

Cold working pressure - 6,000 psi (414 bar).
Lip type elastomer seal protects metal-to-metal seal and seal design reduces turbulence in the line.
Usage mainly in manifold and mud services.
Available with non-pressure thread sealing ends.
