What Is a Tube Fitting Needle Valve?

A Tube Fitting Needle Valve is a manually operated valve with compression (ferrule) ends that directly connect to OD tubing, eliminating the need for threaded joints. It is a preferred choice in instrumentation, pneumatics, and clean-flow control environments due to its ease of installation, zero-leak sealing, and compact design.

Commonly used in pressure gauges, manifolds, control cabinets, sampling lines, and analytical instrumentation loops.
