Low Pressure Fittings
OPTI-LOK low pressure fittings are an excellent choice for making low-pressure connections into 1/4-28 ports. Connections to flat-bottomed ports can be made using OPTI-LOK flat-bottomed ferrules for 1/16” or 1/8” tubing, without the need for pre-flanged tubing ends. OPTI-LOK LP fittings are precision-machined to deliver leak-free, zero-dead-volume connections every time.
