Parker PT-00840 Flareless Bite-type Tube Cap 28mm

Product Description

The PARKER PT-00840 is a flareless bite-type tube cap designed to seal the open end of a 28 mm OD tube without requiring a flared tube end. The bite-type ferrule design grips the tube wall mechanically as the fitting is tightened, creating a secure, leak-resistant closure. This type of cap is commonly used in hydraulic, pneumatic, and fluid-transfer systems to blank off unused ports or protect tube ends during storage, transport, and staged installation. Installation is performed by qualified tradespeople working on instrumentation, industrial fluid lines, or HVAC refrigeration systems where flareless compression-style fittings are specified.

This cap is suited for applications where a 28 mm OD tube must be temporarily or permanently capped in a flareless fitting system. Typical install scenarios include blanking unused branch lines, protecting system endpoints during pressure testing, and capping off service ports on hydraulic or pneumatic circuits. The flareless bite-type connection eliminates the need for a tube flaring tool, making it practical for field service work on existing flareless-style tubing systems.

Key Features

• Flareless bite-type design grips 28 mm OD tubing without tube preparation beyond a clean square cut
• Caps and seals open tube ends to prevent contamination and pressure loss
• Compatible with flareless compression fitting systems using 28 mm OD tube
• Compact, low-profile cap geometry suitable for tight installations
• Sold in packages of 2 per unit

Compatibility

Designed as an OEM-style flareless bite-type end cap for use with 28 mm OD tubing in flareless compression fitting systems.

Installation Notes

Installation should be performed by a licensed mechanic, pipefitter, or HVAC technician familiar with flareless bite-type fitting systems. De-pressurize and isolate the line before installing or removing any tube cap. Ensure the tube end is cut square and is free of burrs before seating the fitting. Do not over-tighten; follow the fitting manufacturer's standard engagement procedure for bite-type ferrule fittings.
