Parker PT-00831 Flareless Bite-type Tube Cap 8mm Steel

Product Description

The PARKER PT-00831 is a flareless bite-type tube cap designed to seal the open end of an 8 mm OD tube in hydraulic and pneumatic fluid-power systems. The bite-type design allows the fitting to grip and seal the tube mechanically without the need for flaring, making it suitable for high-pressure line termination. Constructed from steel, this cap is rated to a maximum working pressure of 500 bar. With an overall length of 18.5 mm, it is a compact, durable component used by fluid-power technicians and industrial maintenance professionals in pressurized tubing circuits.

This tube cap is suited for use in hydraulic systems, pneumatic lines, and industrial fluid-power circuits where open tube ends must be capped and sealed during service, testing, or permanent termination. It is typically installed during system commissioning, maintenance shutdowns, or when a branch line is temporarily or permanently taken out of service. The flareless bite-type design is common in mobile hydraulics, machine tool systems, and process equipment where high-pressure tube fittings are standard.

Key Features

• Flareless bite-type design seals without tube flaring
• Rated to 500 bar maximum working pressure

• Steel construction for durability in high-pressure hydraulic environments
• Overall length of 18.5 mm for compact installation in tight spaces
• Sold in packages of 5 units per package

Compatibility

Designed as an OEM-style replacement or service fitting for metric flareless bite-type tube systems using 8 mm OD tubing rated to high-pressure hydraulic or pneumatic service.

Installation Notes

Installation should be performed by a qualified fluid-power technician or hydraulic systems professional. Always depressurize and isolate the hydraulic or pneumatic circuit fully before removing or installing any tube fitting. Follow the fitting manufacturer torque and assembly procedure guidelines for bite-type fittings, which typically require a pre-swaging step to seat the ferrule before final tightening. Inspect threads and sealing surfaces for damage or contamination prior to assembly.
