Product Description

The TrueSealTM Valve. The most reliable & inert Air Valve for Volatiles Sampling & analysis.

The TrueSealTM Valve requires only 2 in/lbs of torque to seal.

EasyGripTM Knob

If you’re familiar with the TO valves, you’ll surely notice the new and distinctive EasyGripTM knob design. This ergonomic knob provides for a more comfortable experience when processing hundreds of canisters in the lav or having to conduct numerous sampling events in the field. It is designed to contour the hand and provide a more relaxed feel while promoting a more gentle closure. a simple 1/3 turn is all it take to close.

Finger Tightened Cap

Also new on the outside, the TrueSealTM valve comes standard with a finger tightened cap the makes a better seal than the alternative brass caps. There is also far less potential for thread damage with the elimination of wrenches. Thread damage is permanent and translates to replacement cost and time. Tool-free operation is just another way Entech protects your product investments.

Silonite Coating Comes Standard

All TrueSealTM valves will now come standard with the ultra-inert Entech Silonite coating. Silonite prevents the losses of sticky or reactive compounds and provides an inert path from the point of sample introduction to collection.

A Superior Metal to Metal Seal

The primary sealing surface is a stainless steel knife-edged which cuts into a softer nickel valve stop. Because the softer nickel valve stop can yield and conform to particles, the two sealing surfaces are able to fully come together even in the event of surface contamination.
