Nonmetallic 1/4-28 and 10-32 Inline Check Valves

Choose a 5, 6, 7 or 9 Port Manifold to combine several streams into one, or split one fluid stream into several. Each PEEK manifold comes complete with 1/4-28 Super Flangeless™ Fittings for either 1/16" or 1/8" OD tubing, with pressure ratings of 5000 psi (345 bar) and 1000 psi (69 bar), respectively.

Bulkhead mountable 6-Port versions are available, and come with a stainless steel nut and lock washer to hold them in place. These manifolds have 1/2-20 external threads, requiring a 1/2" diameter hole to mount. The recommended torque limit for these products is 15 in.-lbs.

A few useful applications include: multiport mixing chamber, gas sparging splitting union, sample injection onto multi-well plates, or a multiple direction flow path union.

  • Seal off unused ports with any of our 1/4-28 flat-bottom plugs available.
  • To use the PEEK polymer versions of our Tees and Crosses in higher pressure applications, simply replace provided fittings with Super Flangeless Nuts and Ferrules.
  • High Pressure Tees, Crosses and 7-port Manifold (all with 10-32 threaded ports) available.
