Parker PT-00635 Bite-type Tube Male Connector 8mm 1/4 Npt

Product Description

The PARKER PT-00635 is a flareless bite-type tube male connector designed for use in hydraulic and pneumatic tubing systems. The bite-type design uses a ferrule that bites into the tube OD upon tightening, creating a secure, leak-resistant mechanical connection without the need for flaring the tube end. This connector features an 8 mm tube OD on the tube side and a 1/4 inch NPT male thread on the port side, making it suitable for connecting metric tubing to NPT-ported equipment. Installation is typically performed by licensed pipefitters, HVAC technicians, or fluid-power mechanics working on industrial, commercial, or mechanical system piping.

This fitting is well-suited for applications involving metric tubing routed to NPT-threaded ports in hydraulic, pneumatic, or process fluid systems. It is commonly used in commercial HVAC, refrigeration, and industrial fluid-power installations where a reliable, vibration-resistant tube-to-port connection is required. The bite-type engagement provides a robust hold on the tube without welding, brazing, or flaring, making it practical for field assembly and repairs.

Key Features

• Flareless bite-type design eliminates the need for tube flaring before assembly
• 8 mm tube OD connection accepts standard metric tubing
• 1/4 inch NPT male thread for direct connection to NPT-ported equipment
• Ferrule engagement creates a leak-resistant mechanical seal under pressure
• Compact form factor suitable for tight routing in equipment enclosures

Compatibility

Designed as a flareless bite-type replacement or service fitting for systems using 8 mm OD metric tubing and 1/4 inch NPT ported equipment in hydraulic, pneumatic, or process fluid applications.

Installation Notes

Installation should be performed by a qualified pipefitter, HVAC technician, or fluid-power mechanic. Depressurize and isolate the system completely before disconnecting or installing any fittings. Hand-tighten the NPT thread first, then apply wrench turns per standard bite-type fitting assembly practice, being careful not to overtighten and distort the ferrule or thread. Verify all connections for leaks before returning the system to service.
