1/4" x 1/4" Tube x Tube Union Elbow

Joining two lengths of 1/4" tubing around a corner is effortless with the John Guest 1/4" Union Elbow (Tube x Tube). This push-fit elbow accepts 1/4" tubing on both ends and turns the line through a clean 90 degrees, letting you route tubing neatly through tight spaces in reverse osmosis and filtration systems without kinking, crimping, or straining the line.

Clean corners without clamps

Each end features the trusted John Guest collet that grips and seals the tubing automatically the moment it is pushed in, creating a leak-resistant connection that holds firmly under system pressure. As a tube-to-tube union, it connects two tubing runs directly while changing direction, which is ideal for tidy installations behind filters, under sinks, and inside equipment cabinets where space is at a premium and appearance matters.

To assemble, cut both tube ends squarely with a proper tube cutter and push each fully into its collet until it seats against the internal stop, confirming the lock with a gentle tug before pressurizing. To release either tube, simply press the collet ring inward and pull the tubing free. This union elbow is a staple of well-organized RO and filtration plumbing, helping installers turn corners cleanly and connect tubing runs without the kinks or stress that sharp bends would otherwise cause, which protects flow and extends tubing life.
