1/4-28 Flangeless Fittings for 1/16" OD Tubing

For Flat-Bottom Ports

  • Wide variety of materials and geometries to fit most applications
  • NEW for 2009/2010 - fittings and ferrules packaged together for easy ordering convenience
The Upchurch Scientific® Flangeless Fittings are excellent replacements for flanged fittings. Flangeless Fittings are dependable, easy to use and easy to replace.

All nuts have 1/4-28 threads (except XLT-111, which has 10-32 threads). Additionally, all fittings come pre-packaged with appropriate ferrules (1/4-28 threaded fittings are packaged with P-200 ferrules; however, the XLT-111 - a 10-32 threaded fitting - is packaged with P-240 ferrules). Nuts are available in a wide variety of materials, and replacement ferrules are available in ETFE and polypropylene.
