Parker PT-00837 Flareless Bite-type Tube Cap 20 Mm

Product Description

The PARKER PT-00837 is a flareless bite-type tube cap designed to seal the open end of a 20 mm OD tube in hydraulic, pneumatic, or fluid-handling systems. Bite-type fittings use a cutting ring that grips and seals the tube without requiring a flared end, making field installation faster and repeatable. This cap terminates a tube run or blanks off an unused port, preventing contamination and pressure loss. It is sold in a package quantity of two. Plumbers, pipefitters, and hydraulic system technicians typically install this fitting in industrial and mechanical system applications.

This tube cap is suited for use in flareless tube systems where a clean, reliable end seal is required. Typical applications include hydraulic power units, pneumatic distribution lines, and fluid conveyance assemblies in commercial and industrial settings. The bite-type design is common in European-metric tube systems and machine tool hydraulics where 20 mm OD tubing is standard. Installation requires no flaring tool, reducing setup time on the bench or in the field.

Key Features

• Fits 20 mm outside diameter tubing for metric tube systems
• Seals open tube ends to prevent contamination and fluid or pressure loss
• Sold in a package of two units per order
• Compact form factor suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for flareless bite-type tube assemblies using 20 mm OD tubing in hydraulic, pneumatic, and fluid-handling systems.

Installation Notes

Installation is performed by pipefitters or hydraulic technicians. Always depressurize and de-energize the system and relieve all residual fluid pressure before removing or installing tube fittings. Ensure the tube end is cut squarely and is free of burrs before seating the cap. Follow the fitting manufacturer's assembly procedure for proper bite-ring engagement to achieve a leak-free seal.
