Parker A4TEU6-MG Push-to-connect Plug 1/4 Inch Od

Product Description

The PARKER A4TEU6-MG is a push-to-connect tube fitting plug designed to terminate or cap off a 1/4-inch OD tube line without the need for tools or thread sealant. The fitting is constructed from polyoxymethylene (POM), a high-stiffness acetal resin that resists wear and chemical exposure in fluid handling applications. Rated to 300 psi, this plug provides a secure, leak-resistant seal when the tube is inserted fully into the fitting body. It is installed by HVAC technicians, plumbers, and pneumatic system mechanics working with push-to-connect tubing runs where a dead-end cap or temporary line closure is required.

This plug fitting is suited for use in residential and light commercial pneumatic, compressed air, and fluid control systems that rely on push-to-connect tubing. It is a field-use part typically deployed during system commissioning, service, or reconfiguration to cap unused ports or open tube ends. The compact size and tool-free connection make it practical for tight installations and quick service calls.

Installation Notes

This fitting is installed by HVAC technicians, plumbers, or pneumatic system mechanics. Before installation, depressurize and isolate the tubing circuit to zero pressure. Insert the tube fully and squarely into the fitting until it seats to ensure a leak-free connection. To release the tube, depress the release collar evenly before pulling the tube free.
