MGM Model 19A stainless steel needle valves are designed for use in laboratory or other applications where fluid transfer or sampling is required. The 19A stainless steel needle valve is ruggedly built for severe environments of up to 350º F and 1500 psig. The 19A features American Standard ¼” male pipe threads on each end to mate with new or existing fittings or equipment. MGM started manufacturing our 1/4" stainless steel needle valves in the 1950's and has been selling these stainless needle valves by the thousands annually ever since.

While the 1/4" threads on this needle valve will fit with any 1/4" NPT fittings, these valves also feature a tapered machined surface that enables a metal to metal seal with our other fittings, such as our 26E Flexible Connecting Hoses, which have a ball union. 

The 19A needle valve has replaceable Teflon stem tips and o-ring packing. 

NOTE:  DO NOT use a wrench to tighten the stem against the seat.  The 19A is a soft-seated (Teflon to stainless steel) needle valve. Hand wheel should be finger tightened only.  Over tightening the valve will result in unnecessary deformation of the Teflon tip and could permanently damage the stem threads.
