9/16" HP Female Block Tee – 30,000 PSI Stainless Steel 3-Way Fitting

The 9/16" High-Pressure (HP) Female x Female x Female Block Tee is a heavy-duty, three-way fluid distribution component engineered for extreme pressure circuits. Rated for a Maximum Allowable Working Pressure (MAWP) of 30,000 PSI (30K), this block tee allows operators to safely and efficiently split or combine ultra-high-pressure fluid and gas streams in demanding instrumentation, test bench, and subsea control systems.

Machined from a solid block of premium cold-worked 316 stainless steel, this fitting delivers uncompromising structural integrity. All three ports feature 9/16" High Pressure (HP) female connections utilizing industry-standard Autoclave-style coned and threaded technology. When mated with prepared 9/16" HP tubing, collars, and glands, it creates a robust, blowout-proof metal-to-metal seal that remains bubble-tight even under intense mechanical vibration and severe pressure cycling.

Designed for the harshest upstream oil and gas, petrochemical, and industrial environments, the 30K block tee provides superior resistance to chemical attack, environmental corrosion, and mechanical fatigue, making it a critical hub in complex, ultra-high-pressure manifolds.

Features & Benefits

• 30,000 PSI MAWP Rating: Engineered to safely contain and distribute extreme fluid and gas pressures in rigorous industrial applications.

• 3-Way Flow Distribution: Female x Female x Female (FXFXF) configuration allows for seamless splitting or merging of fluid lines.

• Cone & Thread Technology: Employs the highly reliable coned and threaded seating design for a flawless metal-to-metal seal.

• Solid Block Construction: Machined from cold-worked 316 stainless steel billet to prevent distortion or cracking under maximum 30K PSI loads.

• Superior Corrosion Resistance: Excellent defense against harsh offshore environments, corrosive injection chemicals, and sour gas (H2S).

• Standard Interchangeability: Fully compatible with industry-standard 9/16" HP tubing, valves, and fittings (e.g., Autoclave, Butech, Parker).

Specifications & Technical Details

Applications

This 9/16" HP 3-way block tee is an essential component for routing flow in complex ultra-high-pressure systems. Typical uses include splitting flow paths in blowout preventer (BOP) hydraulic power units (HPUs), branching lines on multi-port chemical injection skids, and distributing pressure evenly across multiple test ports on high-volume hydrostatic test benches.

Quality Assurance

Each block tee is CNC-machined to exacting tolerances under rigorous quality control standards. All three coned seating surfaces undergo strict visual inspection and dimensional gauging to ensure flawless metal-to-metal seating and prevent galling. All 316 SS materials are fully traceable, ensuring the component provides reliable, fail-safe performance at its maximum 30,000 PSI operational limit.
