High-Pressure Quick Disconnect Coupler – M9 (9/16" Type M) Female, Back with Check Valve | 30,000 PSI

The High-Pressure Quick Disconnect Coupler, M9 Female with an M9 Back and Integrated Check Valve, is an ultra-durable, precision-engineered fluid transfer component designed for extreme hydrostatic testing and ultra-high-pressure hydraulic applications. Engineered to safely contain and control fluid at working pressures up to 30,000 PSI, this quick disconnect (QD) coupler is an essential asset for high-pressure test benches, hydrostatic pump units, and heavy-duty tensioning equipment.

This specific coupler features a Type M9 (9/16" Type M) female connection profile designed for seamless, push/pull quick-disconnect operation. The back of the coupler utilizes a standard M9 connection for reliable integration into 9/16" Type M high-pressure hose assemblies and tubing configurations.

Crucially, this model is equipped with a high-performance Integrated Check Valve. This built-in safety feature automatically shuts off fluid flow the instant the coupler is disconnected. This prevents hazardous high-pressure blowback, minimizes fluid loss, and maintains system pressure integrity on the supply side, allowing operators to safely and cleanly swap lines or tools without completely depressurizing the main source.

Features & Benefits

• 30,000 PSI Capacity: Rated for extreme-pressure environments up to 30,000 PSI, making it ideal for hydrostatic testing, waterjetting, and ultra-high-pressure hydraulic tooling.

• Integrated Check Valve: Automatically seals the line upon disconnection to prevent pressure loss, protect operators from fluid blowback, and eliminate messy spillage.

• Type M9 (9/16" Type M) Compatibility: Features a female M9 quick-disconnect profile and an M9 back connection for seamless integration into industry-standard 9/16" Type M high-pressure systems.

• Push/Pull Quick Disconnect: Allows for fast, secure makeup and breakout by hand, drastically reducing rig-up time and operator fatigue during frequent line changes.

• Heavy-Duty Stainless Steel Construction: Manufactured from high-strength, corrosion-resistant stainless steel alloys to withstand galling, extreme mechanical stress, and harsh test fluids.

Specifications & Technical Details

Applications

This 30K PSI check-valved coupler is widely utilized in industrial environments requiring rapid, safe connections under extreme pressure. Typical applications include connecting ultra-high-pressure hoses to hydrostatic test pumps, wellhead testing panels, hydraulic bolt tensioners, blowout preventer (BOP) test skids, and precision waterjet cutting systems.

Quality Assurance

All our ultra-high-pressure quick disconnects are manufactured to exact tolerances using premium stainless steel. Each coupler undergoes rigorous dimensional inspection and hydrostatic pressure testing prior to shipment to ensure absolute safety, structural integrity, and flawless check valve engagement under maximum working loads.
