9/16" High-Pressure (HP) Collar – 60,000 PSI Cone & Thread Fitting

The 9/16" High-Pressure (HP) Collar is a critical instrumentation component utilized in ultra-high-pressure coned and threaded tubing systems. Engineered to withstand extreme operating pressures up to 60,000 PSI, this collar acts as the primary load-bearing shoulder within the connection. It allows the heavy-duty gland nut to securely drive the coned tip of the tubing into the mating female port, creating a highly reliable, bubble-tight metal-to-metal seal.

Manufactured from premium cold-worked 316 stainless steel, this collar is designed specifically for 9/16" outer diameter (OD) high-pressure tubing. A defining feature of the HP collar is its precision-machined internal left-hand threads. During assembly, the collar is threaded onto the left-hand threads of the prepared tubing. When the right-hand threaded gland nut is subsequently tightened over it, the opposing thread directions prevent the collar from backing off, ensuring a stable and vibration-resistant connection.

Built for the most demanding fluid and gas control environments, the 9/16" HP Collar is an industry-standard fitting for test benches, chemical injection skids, and subsea control panels where absolute pressure integrity is non-negotiable.

Features & Benefits

• 60,000 PSI Pressure Rating: Engineered to handle ultra-high-pressure environments, providing a blowout-proof structural shoulder for HP connections.

• Left-Hand Internal Threads: Designed to thread onto the tubing opposite to the gland nut, preventing rotational loosening during make-up and operation.

• Cold-Worked 316 Stainless Steel: Delivers exceptional tensile strength and superior resistance to corrosion, chemical attack, and mechanical fatigue.

• Metal-to-Metal Seal Enabler: Translates the torque from the gland nut into maximum axial force, ensuring perfect engagement of the coned tubing tip.

• High-Vibration Resistance: The interlocking mechanical design ensures that connections remain secure even in heavy cyclic-pressure and high-vibration applications.

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

Specifications & Technical Details

Applications

This 9/16" HP collar is essential for making secure connections in ultra-high-pressure instrumentation and control lines. Typical applications include high-pressure hydraulic test benches, subsea umbilical termination assemblies (SUTAs), chemical injection skids, waterjet cutting machinery, and deepwater blowout preventer (BOP) control systems.

Quality Assurance

Each collar is manufactured to exacting tolerances under rigorous quality control standards. The internal left-hand threads are precisely gauged to ensure smooth assembly onto high-pressure tubing. All materials are fully traceable, and the components undergo strict inspection to guarantee structural integrity and fail-safe performance at 60,000 PSI.
