Quick Coupling / OPW Autolok Coupler

High-Risk Chemical Transfer: Ideal for handling hazardous, toxic, volatile, or high-value chemicals where a line disconnect would cause severe environmental or safety hazards.

High-Vibration Systems: Widely installed on bulk product pumping manifolds, offshore applications, and high-frequency loading arms.

Process Plant Piping: Used to transition permanent male-threaded piping into an ultra-secure, self-locking quick-connect terminal.

Coupler Type: 733DL Autolok (Female Coupler with Female NPT Thread)

Body & Arm Material: Stainless Steel (SUS 316) (Provides ultimate mechanical strength, superior wear life, and exceptional resistance to highly aggressive chemicals, acids, and caustics).

Locking Mechanism: Patented Autolok™ Self-Locking Arms (Automatically lock into place upon closure; requires a intentional manual pull-release to reopen).

Thread Standard: Female NPT (National Pipe Thread) for secure, leak-proof tapered thread engagement.

Standard Gasket: Buna-N (Premium oil- and weather-resistant elastomer; alternative specialized compounds are available for highly aggressive media).

Max Working Pressure: 16 bar (Engineered to withstand higher pressure ratings than standard commercial camlocks).

Size Range: 1″ to 4″

Brand: OPW (United States)

Fail-Safe Autolok™ Technology: The arms feature an internal locking finger that snaps securely shut against the adaptor shoulder. The coupler cannot be opened accidentally by being bumped, dragged, or shaken—providing absolute peace of mind for operators.

No Clips or Pins Required: Streamlines connection times and improves safety by eliminating the need for separate, easily lost safety clips or lanyards.

16-Bar Heavy-Duty Rating: Precision cast and machined from solid 316 Stainless Steel, allowing it to maintain an uncompromised seal under demanding 16-bar structural pressure parameters.

Universal Interchangeability: Fully compliant with standard military and international specifications (A-A-59326 / MIL-C-27487) dimensions, enabling it to mate with any standard compliant male adaptor while upgrading the connection to a self-locking safety system.
