Non-spill couplings
NSH
NSH is the general purpose version of the pressure-balanced ChemQuik CQG couplings. The flow path contains no springs and no metal, which gives high flow capacity and broad chemical resistance. The coupling can be disconnected and reconnected under pressure without spilling. Polypropylene body, EPDM or FKM seal, terminations from 3/8" to 3/4", rated from vacuum to 8.3 bar and 0 to 49 °C.

Frequently asked questions
- How does NSH differ from CQG?
- NSH is the general purpose version of the same pressure-balanced non-spill design, in polypropylene with EPDM or FKM seals. CQG is tailored to particularly demanding chemical applications.
- Why is the flow rate so high?
- There are no springs or metal parts in the flow path to restrict the cross-section. The fluid passes through the coupling almost unobstructed.
- Can NSH be disconnected under pressure?
- Yes, the pressure-balanced design lets you disconnect and reconnect NSH under pressure without spilling.
- Are closure caps available?
- Yes, the series includes caps and plugs to seal open coupling halves.
