Pro-source 2555511663PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555511663PRO is a push-to-connect tube fitting with a universal thread connection, constructed from nickel-plated brass. It accepts a 12 mm outside-diameter tube and is rated for service up to 250 psi. The fitting uses a Buna-N O-ring for a reliable, leak-resistant seal. Designed for quick installation without the need for threading tools, it is commonly installed by HVAC technicians, plumbers, and maintenance technicians working on compressed air lines, water distribution, or fluid-transfer systems. The nickel plating provides corrosion resistance suited to both wet and dry service environments.

This fitting is used in light commercial and residential applications where fast tube connections to threaded ports are required. Typical installations include compressed air distribution lines and water service plumbing. The 1/4 inch universal thread configuration makes it adaptable to a range of standard threaded ports. It is sold in a package quantity of three units, making it practical for jobs requiring multiple connections at a single service call or installation.
