Parker 1/4" Tube x 1/4" Male Connector

The Parker 1/4" Tube x 1/4" Male Connector from Parker Hannifin Corp. is a precision push-to-connect fitting that joins 1/4" tubing to a 1/4" male iron pipe thread. Backed by Parker's reputation for engineered fluid-system components, it is a dependable choice for connecting water lines to threaded ports in filtration and reverse osmosis systems, where a clean, reliable transition between tubing and threaded hardware is essential.

Built from POM polymer, a rigid engineering plastic (acetal) known for dimensional stability and chemical resistance, this connector delivers reliable performance in continuous-duty water applications. The push-in tube side grips and seals 1/4" tubing automatically the moment it is seated, while the threaded end mates with tapped ports on filters, valves, and manifolds, removing the need for stacked adapters.

Key Features

• Connection: Tube x MIPT, both 1/4"
• Straight male connector for tube-to-thread transitions
• Molded from durable POM polymer (acetal)
• Push-fit tube end seats quickly without tools
• Demountable for clean, repeatable servicing
• Reusable across repairs and reconfigurations

To install, wrap the male thread with PTFE tape and hand-tighten it into the port, snugging just past finger-tight to avoid cross-threading the plastic. Then cut your 1/4" tube square and free of burrs, push it fully into the collet until it bottoms out, and confirm the grip with a gentle tug. The fitting is demountable, so the tube can be released for servicing by depressing the collet, then reconnected when the work is done. POM polymer's dimensional stability helps the connector hold its shape and maintain a consistent seal over years of continuous service with treated water, while its chemical resistance suits it to the conditions found in filtration and RO plumbing. For a high-quality, leak-free tube-to-thread connection in residential water treatment systems, this Parker male connector is a trusted, durable component.

Parker's fluid-system fittings are widely used in demanding industrial and OEM applications, so applying the same engineering to a residential water connector means homeowners and installers benefit from proven design tolerances. Whether you are assembling a new RO system or repairing an existing filtration setup, this male connector offers the precision fit and consistent sealing that make push-fit plumbing both fast to install and dependable over years of service.
