Mininert™ Valves with Threads from VICI Precision Sampling

Mininert valves with threaded fittings

Our threaded designs offer positive on/off fluid control as an in-line valve or syringe access as a termination valve at a sample point.

In-line valves are 1/4-28 male to male or 1/4-28 female to female. Termination valves are offered in 1/4-28 male or female and 1/8" NPT male or female.

MORE INFORMATION

TEMPERATURE

Mininert valves can be used at temperature up to 105°F. However, after use at high temperatures, the valve may leak slightly when cooled to room temperature.

MATERIALS

PTFE is highly inert and may be used with most common materials. It is particularly useful for working with most acids and organic solvents. However, problems may be encountered when used with organometallics and some strong bases. We recommend actual exposure tests before use with any material.

PRESSURE

The sealing ability of Mininert valves is more than adequate for con-taining most volatile liquids and gases at low pressures. Mininert valves have been used as high as 120 psi without leakage, but this is not a recommendation for pressurizing glass containers to these levels. Such pressurization of glass containers can be extremely dangerous.
