The P-WAT-2323 (SMC Part Number: KQ2L13-35AS) is a versatile, compact fitting that bridges the gap between rigid threaded components and flexible tubing. Its 90° elbow shape allows for connections in tight spaces and helps manage tube routing.


Connection Details


  • Side A (Threaded): 1/4" Male NPT (MNPT). This end connects to threaded ports on valves, manifolds, or equipment. It includes pre-applied thread sealant for quick, positive sealing.
  • Side B (Tubing): 1/2" Push-to-Connect. This end accepts 1/2-inch OD tubing (Nylon, Soft Nylon, Polyurethane, FEP, PFA). The connection provides positive sealing under pressure without reducing flow.
  • Release Collar: The quick connect mechanism features a release collar that allows for easy removal of the tube without causing damage.

Construction and Design


  • Material: The fitting body is constructed from Brass, an alloy known for its strength and corrosion resistance against water, heat, and chemicals.
  • Rotational Stud: The threaded stud allows for the rotation of the elbow body, providing ease of installation and alignment in confined or complex piping layouts.
  • Versatile Media: Suitable for use with both air and non-potable water systems.
