This 1/4-28 fittings connection kit for 1/8" OD tubing is made of Delrin to ensure its high chemical resistance. Reusable, highly versatile, and compatible with a large range of microfluidic equipment, it is an alternative to our 1/4-28 to 1/16" OD fittings for your tubings.
This kit contains 10x 1/4-28 to 1/8" OD fittings and 10x 1/8" OD ferrules.

A set of 1/4-28 flat-bottom fittings to tightly hold your 1/8" OD rigid tubing.

  • Robust and durable: the nuts and ferrules are respectively made of Delrin and ETFE
  • Highly resistant
  • Reusable
  • Compatible with 1/8" OD tubing

Connect any device (reservoir, bubble trap,...) to your 1/8" OD tubing easily by screwing the fitting and ferrule in any 1/4-28 UNF thread port.

Flangeless fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits:

  • Convenience: Flangeless fittings are easy to use. Just slip the nut and ferrule over the tubing and finger-tighten the assembly into your receiving port. In tests, it is shown that the ideal amount of torque to achieve expected part performance should be approximately 3–4 in-lbs (0.34–0.45 N·m).
  • Minimal downtime: Component replacement is quick, taking only a few seconds unlike the significant time required to flange tubing.
  • Cost-effectiveness: Repairing a flanged tubing assembly requires a costly flanging tool or the purchase of a complete replacement assembly, including a new length of tubing and a set of fittings. The Flangeless fittings system typically requires only one new ferrule at minimal cost when repairing a connection.
