This Push-To-Connect fitting is used for the air actuated valve. It has a 5/16" Male NPT on one end and a 1/4" tube fitting on the other end. The Push-To-Connect style allows for easy installation of air lines with no tools needed. These fittings are reusable by simply releasing the tubing from the fitting.


Key features and benefits include:


  • Built for Chemical & Moisture Exposure: Standard hardware store fittings quickly corrode or degrade when exposed to recycled car wash water and aggressive chemical concentrates. This Hydra-Flex fitting features premium internal locking claws and synthetic seals engineered to prevent chemical degradation.
  • Instant, Leak-Free Sealing: The 10-32 male thread includes a premium integrated sealing ring, ensuring an absolute airtight connection the moment it is threaded into your air valve or solenoid block.
  • True Push-to-Connect Convenience: No tools, sleeves, or compression nuts required. Simply cut your 1/4" poly or nylon pneumatic tubing flush, push it into the collar, and the internal stainless steel gripping teeth lock it securely in place.
  • Optimized for Solenoid & Air Valve Banks: The compact, low-profile hex design allows for easy installation in tight, multi-valve manifolds where center-to-center spacing is extremely limited.
  • End 1: 5/16" Male NPT
  • End 2: 1/4" Push-To-Connect Tube
  • Connection Type: Threaded-to-Tube
  • Max Pressure: 150 PSI
  • Thread Size: 10-32 UNF (Male)
  • Tubing Size: 1/4" Outside Diameter
  • Fluid/Gas Type: Compressed Air / Pneumatics
  • Body Material: Heavy-duty, corrosion-resistant composite and nickel-plated brass components
  • Seal Type: Integrated O-ring seal for instant, airtight seating without the need for messy thread sealant
