HAMMER UNIONS

Hammer lock unions are available in a variety of working pressures, Pipe Nut
and with metal seals or with various elastomeric seals. Only the most Part No. Size Length Radius
commonly stocked hammer unions are listed here. Please contact us G0808HLU-F200
for other configurations and working pressures.
Figure 200 unions are recommended where working pressures* do
not exceed 2000 psi. They are popular for low pressure rig piping.
Nuts are ductile iron up to 21⁄2" and steel in larger sizes. Bodies are
forged steel to 4" and cast steel above 4".

Figure 602 units are rated to 6000 psi and have a nitrile seal ring
to improve the steel to steel seating. The nuts and bodies are all
forged steel except 4" bodies are alloy steel.

••••••••••••••••••••••••••• WARNING ••••••••••••••••••••••••••••
Never assemble any combination of male sub, wing nut, or segments that are not absolutely positively identified and
assured to be all parts are identical in figure number, size, and pressure rating. Mismatched components will result in
hazardous connections that can result in catastrophic failure. Hammer lock union components that cannot be positively
identified must never be used.
Never expose standard service products to sour gas fluids.
