Parker PT-00591 Flareless Bite-type Male Connector 6mm 3/8 Bspp

Product Description

The PARKER PT-00591 is a flareless bite-type tube male connector designed for use in hydraulic and instrumentation tubing systems where a reliable, leak-free connection is required without flaring the tube end. The fitting accepts a 6 mm tube outside diameter and threads into a 3/8 BSPP female port. Bite-type fittings use a ferrule that bites into the tube wall on assembly, creating a mechanical grip and seal without additional sealing compounds in most applications. This connector is suited for professional tradespeople working on fluid power, pneumatic, or instrumentation lines.

This fitting is typically used in industrial fluid systems, HVAC refrigeration circuit accessories, pneumatic control lines, and hydraulic equipment where metric tubing meets BSP-ported components. The 6 mm tube OD accommodates common metric instrument and process tubing. The 3/8 BSPP male thread is widely found on valves, manifolds, cylinders, and control blocks in European-standard and globally specified equipment. Each package contains 5 connectors with a minimum order quantity of 1 package.

Key Features

• Flareless bite-type design eliminates the need for tube flaring tools during assembly
• 6 mm tube outside diameter accommodates standard metric instrument tubing
• 3/8 BSPP male thread for connection to BSP-ported valves, manifolds, and housings
• Ferrule-grip seal provides a secure mechanical connection under pressure
• Packaged in quantities of 5 per package for convenience on multi-connection jobs

Compatibility

Designed as an OEM-style replacement or service fitting for fluid power, pneumatic, and instrumentation systems using 6 mm OD metric tubing and 3/8 BSPP female-ported components.

Installation Notes

Installation should be performed by a qualified pipefitter, fluid power technician, or instrumentation mechanic. Depressurize and isolate the system completely before removing or installing any fittings. Ensure the tube end is cut square and deburred before inserting into the fitting body to allow the ferrule to seat correctly. Consult applicable industry codes and the fitting manufacturer torque and assembly instructions for proper make-up procedure.
