Description
Push-in quick-screw stainless steel tube fittings speed tube install on air and water lines without flare tools. FerruleX covers OD 4–16 mm and 1/8"–1/2" in SS304/SS316/SS316L: insert the tube, seat fully, then tighten the nut. Pneumatic cabinets, cooling loops and OEM machines that change tubing often favor this style over full compression. Quick-screw lines are pneumatic-class fittings: maker stainless push-in series publish roughly 10–16 bar (about 145–230 psi), with tube 4–12 mm / 1/8–1/2 inch typical. Values are class-typical references for this configuration; tube OD, series and pressure class are confirmed on the RFQ. Send your tube OD list to FerruleX for a factory RFQ; stocked sizes ship fast. Do not reuse a nut that was over-tightened onto scored tube — grab quality suffers.
Quick-screw joints forgive soft tube better than double-ferrule bites, but they still need a square cut and full insertion depth. Do not reuse a nut that has been over-tightened onto scored tube. FerruleX can kit elbows and tees with the same OD on one RFQ for a complete pneumatic panel.
