John Guest Reducing Tee 3/8" x 3/8" x 1/4" Push Fit PI301208S

The John Guest PI301208S Reducing Tee is a high-quality push-fit fitting designed to connect two 3/8" OD tubes with a reduced 1/4" OD branch connection. Manufactured from durable grey acetal copolymer, it provides a fast, secure and reliable connection for water treatment, potable water, beverage dispense and other fluid-handling applications.

John Guest push-fit technology allows tubing to be connected simply by pushing it fully into the fitting, creating a secure, leak-tight seal without the need for tools, sealants or specialist equipment. The fitting can also be disconnected and reused, making installation, servicing and system alterations quick and straightforward.

The unique John Guest collet design securely grips the tubing without deforming it or unnecessarily restricting flow. Its corrosion-resistant construction makes the PI301208S particularly suitable for water treatment systems and equipment where reliable long-term performance is required.
