The PARKER PT-00500 is a flareless bite-type tube swivel connector designed for secure, leak-resistant tube-to-port connections in fluid power and instrumentation systems. The bite-type design uses a ferrule that grips and deforms around the tube OD during assembly, eliminating the need for flaring the tube end. This connector accepts 6 mm outside-diameter tubing and threads into a 1/8 BSPP female port. It is typically installed by licensed plumbing, HVAC, or fluid-systems technicians working on hydraulic lines, pneumatic circuits, process instrumentation, or refrigerant-adjacent control tubing where metric tube and BSP threaded ports are specified.
This fitting is suited for applications where swivel movement is needed at the port connection to prevent tube stress or misalignment during installation. The 1/8 BSPP thread type is commonly found on European-standard equipment, imported HVAC controls, and hydraulic manifolds. The 6 mm tube OD is a standard metric size used in pneumatic and light hydraulic circuits. This part ships in package quantities of five, making it practical for panel builds and multi-connection service jobs that require several identical fittings.
Designed for use with 6 mm outside-diameter rigid or semi-rigid tubing on systems with 1/8 BSPP female threaded ports. Consult system documentation to confirm tubing material compatibility and working pressure ratings before installation.
Installation should be performed by a qualified technician familiar with fluid power or pneumatic system assembly. Depressurize and isolate the circuit completely before removing any existing fittings or connecting new ones. Ensure the tube end is cut square and is free of burrs before insertion into the fitting body. Torque the fitting nut by hand until resistance is felt, then follow the fitting manufacturer's assembly procedure for bite-type ferrule engagement — do not rely on feel alone to confirm a leak-free joint; pressure-test the circuit after assembly.
