30,000 PSI Quick Connect Nipple (No Check Valve) x 9/16" HP Male – Stainless Steel Fitting

The 30,000 PSI Quick Connect Nipple (Without Check Valve) to 9/16" High-Pressure (HP) Male is an ultra-high-pressure, straight-through coupling plug designed for rapid integration into severe-service fluid systems. Rated for an extreme Maximum Allowable Working Pressure (MAWP) of 30,000 PSI (30K), this precision fitting connects quick-release systems directly to industry-standard 9/16" HP coned and threaded tubing, making it an essential component for hydro-demolition, waterjet cutting, and high-volume hydrostatic testing equipment.

Unlike valved couplers, this "unvalved" or "straight-through" nipple does not contain an internal check mechanism. This design provides an unrestricted flow path, significantly reducing pressure drop and turbulence, which is critical for maximizing power output in high-velocity waterjet and blasting applications. It is typically installed on the downstream tool, lance, or manifold side of the connection where fluid shut-off upon disconnection is either handled by a mating valved coupler or is not required.

The opposite end features a precision-machined 9/16" HP Male connection. Utilizing standard cone-and-thread technology, it provides a highly reliable, blowout-proof metal-to-metal seal. Manufactured from high-strength, corrosion-resistant stainless steel, this nipple is engineered to endure intense mechanical stress, heavy vibration, and the abrasive conditions of industrial surface preparation and offshore maintenance.

Features & Benefits

• 30,000 PSI MAWP Rating: Engineered to safely contain and transmit ultra-high fluid pressures in the most demanding industrial applications.

• Straight-Through Flow (No Check): Unvalved design eliminates internal flow restrictions, maximizing fluid velocity and minimizing pressure drops.

• 9/16" HP Male Connection: Features a standard coned and threaded interface for a secure, metal-to-metal seal on high-pressure tubing and manifolds.

• Quick Disconnect Functionality: Allows for rapid, tool-free connection and disconnection when paired with a matching 30K quick coupler, minimizing operational downtime.

• High-Strength Stainless Steel: Delivers superior tensile strength, impact resistance, and long-lasting protection against corrosion and chemical attack.

• Optimized for Dynamic Loads: Built to withstand the extreme cyclic pulsing and vibration inherent to heavy-duty pumping operations.

Specifications & Technical Details

Applications

This 30K PSI quick connect nipple is critical for ultra-high-pressure applications that require unrestricted fluid flow and frequent tool changes. Typical uses include mounting on the inlet of hydro-blasting lances and waterjet nozzles, attaching high-volume test hoses to hydrostatic pressure benches, and integrating specialized cleaning tools into offshore maintenance systems.

Quality Assurance

Each quick connect nipple is CNC-machined to exacting tolerances under rigorous quality control standards. The 9/16" HP coned seating surface and threads undergo strict visual and dimensional gauging to ensure a flawless metal-to-metal seal. All stainless steel materials are fully traceable, ensuring the component provides reliable, fail-safe performance at its maximum 30,000 PSI operational limit.
