Description: Miniature compression fitting with ¼-28 external thread, for 1/8″ OD stiff plastic or metal tubing.

Max Pressure Rating: 1,000 psig in brass and 3,000 psig in stainless steel, when used with high pressure metal tubing. When using stiff plastic tubing, the burst pressure of the tube is typically the limiting factor.
