NLB: Couplings, Fittings & Adapters

Couplings

NLB offers a variety of couplings in working pressures up to 20,000 psi (1,400 bar). Couplings are available in quick-disconnect (sleeve-lock) and wing union (hammer-lock) styles. Inexpensive O-rings are available for repairing all NLB Couplings.

Coupling shields

NLB high-pressure coupling shields provide a secondary means of protection in the event of coupling release. Hoses stay in place while high-pressure water is deflected.

Part No	Max. Pressure
CS-22	10,000 psi (700 bar)
CS20-22	20,000 psi (1,400 bar)

Whipcheck™

The Whipchek cable* is used to secure each high-pressure hose connection. In the event of coupling release, the cable limits hose movement.
