9/16" High-Pressure (HP) 2-Piece Plug Assembly – 60,000 PSI Stainless Steel Port Plug

The 9/16" High-Pressure (HP) 2-Piece Plug Assembly is a critical pressure-containment fitting designed to securely seal and blank off unused 9/16" HP female ports in ultra-high-pressure manifolds, valves, and cross fittings. Rated for an extreme Maximum Allowable Working Pressure (MAWP) of 60,000 PSI (60K), this assembly provides absolute, bubble-tight isolation in systems utilized for high-pressure testing, chemical injection, and waterjet cutting.

This specific "2-piece" design consists of a solid, precision-machined coned plug and a heavy-duty threaded gland nut. Unlike standard tubing connections that require three pieces (tubing, collar, and gland), the solid plug features an integrated, machined load-bearing shoulder. This eliminates the need for a separate threaded tubing collar. When the gland nut is tightened into the female port, it drives the coned tip of the solid plug directly into the mating seat, creating a flawless, blowout-proof metal-to-metal seal.

Manufactured from premium cold-worked 316 stainless steel, this plug assembly delivers exceptional tensile strength, resisting deformation under extreme 60K mechanical loads while providing superior protection against harsh, corrosive operational environments.

Features & Benefits

• 60,000 PSI MAWP Rating: Engineered to safely contain ultra-high fluid and gas pressures, ensuring uncompromising safety in extreme industrial applications.

• 2-Piece Design (Plug + Gland): Integrated shoulder design eliminates the need for a separate collar, simplifying installation and reducing component count.

• Positive Isolation: Provides a highly reliable, blowout-proof dead-end for 9/16" High-Pressure (HP) female ports to prevent fluid loss or pressure drops.

• Cold-Worked 316 SS Construction: Delivers exceptional structural integrity, fatigue resistance, and protection against chemical attack and sour gas (H2S).

• Metal-to-Metal Seal: Precision-machined cone angle guarantees perfect engagement with the mating female port, maintaining a bubble-tight seal even under heavy vibration.

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

Specifications & Technical Details

Applications

This 9/16" HP 2-piece plug assembly is essential for operations requiring the secure termination of ultra-high-pressure circuits. Typical applications include blanking off unused ports on multi-way cross or tee fittings, capping sample points on high-pressure chemical injection skids, and dead-ending manifold lines on hydrostatic test benches during pressure hold testing.

Quality Assurance

Each plug assembly is CNC-machined to exacting tolerances under rigorous quality control standards. The coned sealing surface undergoes strict visual and dimensional gauging to ensure a flawless metal-to-metal seal that prevents galling and leakage. All 316 SS materials are fully traceable, ensuring the component provides reliable, fail-safe performance at its maximum 60,000 PSI operational limit.
