Description

The ARF70-3/8F 3/8 inch Female High-Pressure Quick Coupling is engineered for professionals who operate in environments where connection failure is not an option. Designed to withstand working pressures up to 10,150 PSI (700 bar), this coupling provides a dependable interface for ultra high-pressure water, hydraulic, and industrial fluid systems. Its rugged stainless-steel construction, precision machining, and advanced sealing architecture make it suitable for the most demanding applications, including industrial cleaning, hydrostatic testing, and water jetting operations.

Unlike conventional quick-connect fittings intended for moderate pressures, this coupling uses a twist coupler with screw mechanism to create a secure mechanical lock between the female body and the mating male plug. This threaded engagement is specifically designed to handle extreme pressure loads and torsional forces generated in high-performance systems. By distributing stress along the threaded interface, the coupling maintains stability even under pulsing pressure, vibration, and sudden load changes that would compromise standard connectors.

The hardened stainless-steel body resists corrosion, abrasion, and environmental damage, ensuring long-term reliability in outdoor, marine, and chemical-exposed conditions. Precision-machined internal surfaces preserve sealing integrity across thousands of connection cycles, while the optimized internal bore promotes efficient fluid flow with minimal turbulence or pressure drop. This allows equipment to operate at peak performance without unnecessary energy loss.

A dual-seal configuration consisting of a high-performance O-ring and backup ring provides redundant leak protection. The recessed seal chamber shields these components from wear and contamination, extending service life and maintaining consistent sealing performance. The screw-lock design also enables controlled connection and disconnection, improving safety by preventing sudden release under pressure.

Operators benefit from a knurled exterior that enhances grip during installation and removal, even when wearing gloves or working in wet conditions. The coupling’s compact 3/8 inch size allows integration into tight manifolds, portable equipment, and specialized tooling without sacrificing flow capacity. Its vibration-resistant design makes it especially valuable for mobile systems, heavy machinery, and field service equipment.

Whether used in pressure washing systems, hydraulic circuits, sewer jetting rigs, or testing facilities, the ARF70-3/8F delivers the durability and connection security required for high-risk, high-pressure operations. For professionals who demand uncompromising performance and safety, this coupling represents a critical component in maintaining system reliability, protecting equipment, and ensuring consistent operational results.
