9/16" HP Male x 1" Type M Male Hex Nipple – 40,000 PSI Stainless Steel Crossover Adapter

The 9/16" HP Male x 1" Type M Male Hex Nipple is a heavy-duty crossover adapter specifically engineered to bridge rigid high-pressure instrumentation systems with large-bore, high-pressure flexible hoses. Rated for a Maximum Allowable Working Pressure (MAWP) of up to 40,000 PSI (40K), this specialized fitting is an essential component for high-volume hydro-blasting, waterjet cutting, and ultra-high-pressure hydrostatic testing operations.

One end features a precision-machined 9/16" High-Pressure (HP) Male connection, utilizing the industry-standard Autoclave-style coned and threaded design to deliver a blowout-proof, bubble-tight metal-to-metal seal. The opposing end features a 1" Type M Male connection, designed to mate flawlessly with heavy-duty high-pressure hose swivels. A robust hexagonal center body provides a wide, flat gripping surface, allowing operators to apply maximum wrench torque for secure installation without damaging the fitting's structural integrity.

Manufactured from premium cold-worked stainless steel, this hex nipple provides exceptional tensile strength, impact resistance, and durability against the extreme vibration and cyclic pulsing typical of high-horsepower waterjetting pumps and test benches.

Features & Benefits

• 40,000 PSI MAWP Rating: Engineered to safely contain and transmit ultra-high fluid pressures, ensuring uncompromising safety in extreme industrial applications.

• Crossover Functionality: Seamlessly transitions fluid from rigid 9/16" HP coned and threaded tubing/manifolds to flexible 1" Type M hose assemblies.

• Hexagonal Center Body: The integrated hex profile allows for easy, slip-free wrenching during make-up and break-out, reducing installation time and preventing tool damage.

• Autoclave-Style HP Connection: Features a standard coned and threaded interface for a highly reliable metal-to-metal seal on the rigid tubing side.

• High-Strength Stainless Steel: Delivers superior tensile strength and excellent resistance to corrosion, harsh chemical exposure, and mechanical fatigue.

• Optimized for Dynamic Loads: Built to withstand the intense vibration and hydraulic shock inherent to continuous, heavy-duty pumping operations.

Specifications & Technical Details

Applications

This 9/16" HP x 1" Type M hex nipple is critical for operations requiring secure integration between high-pressure pump manifolds and flexible hose arrays. Typical uses include connecting 1-inch hydro-blasting delivery hoses to rigid pump discharge manifolds, routing high-volume fluids on ultra-high-pressure test benches, and integrating specialized heavy-duty cleaning tools into offshore maintenance skids.

Quality Assurance

Each crossover adapter is CNC-machined to exacting tolerances under rigorous quality control standards. The 9/16" HP coned seating surface and the Type M sealing face undergo strict visual and dimensional gauging to ensure flawless metal-to-metal engagement. All stainless steel materials are fully traceable, guaranteeing reliable, fail-safe performance under extreme field conditions.
