Hiltap/OPW RapidLOK™ Series Safety Quick Coupling

Hiltap/OPW RapidLOK™ Series Safety Quick Coupling

The Hiltap RapidLOK™ series is an all-purpose, high-performance, quick coupling designed for leak-proof sealing through a wide range of high-pressure and temperature applications.

Designed to replace conventional “cam and groove” couplings, the Hiltap safety coupling is engineered with twist-to-seal technology for increased efficiency and accident-free disconnect.

Frequently Asked Questions

Find quick answers to some of the most common questions

How does the Hiltap RapidLOK coupling improve safety during disconnection?

RapidLOK couplings incorporate a safety ring mechanism that prevents the coupling halves from fully separating until residual line pressure is vented. This design protects operators from pressure spray‑back and hose whip during disconnection.

What sealing technology is used in the RapidLOK coupling?

RapidLOK uses a reusable metal‑to‑metal wedge seal engineered for high‑integrity containment. Seal materials are selected for hardness and thermal expansion characteristics. An optional elastomer O‑ring can be added as a secondary environmental seal.

Does the RapidLOK coupling restrict flow or reduce internal diameter?

No. RapidLOK couplings are designed with a full‑bore, non‑restrictive internal diameter that matches the connecting pipe size. This allows unrestricted flow and supports full pigging capability.

How does RapidLOK prevent galling on stainless-steel components?

Stainless steel RapidLOK components receive a nitriding surface treatment that hardens the metal and prevents thread galling, seizing, and wear during repeated connections and disconnections.
