The retained brass collet gives superior tube anchorage. Available metric tube OD. are 4mm 5mm 6mm 8mm 10mm 12mm 16mm. Imperial tube OD. are 1/8" 5/32" 3/16" 1/4" 5/16" 3/8" 1/2".
Inch-NPT Pneumatic Fittings
Pneuflex Inch Tube with NPT thread pneumatic fittings (pneumatic composite push in fittings, push to connect fittings) are very popular in USA, Canada, Mexico, Peru, Colombia and Brazil. Tube O.D sizes include 1/8", 5/32", 3/16", 1/4", 5/16", 3/8" and 1/2", threads sizes are NPT1/8", NPT1/4", NPT3/8" and NPT1/2".
