Glass Impingers

To collect a good sample, tubing must connect to the impinger port fittings in a manner that is leak-free and secure. When assembling the impinger, secure tubing to each fitting by tightening the supplied nut. Test each connection by pulling gently on the tubing after assembly. If tubing pulls away from the fittings, apply more force when tightening each nut. The amount of force required during each assembly may vary depending on the tolerances of the fittings and the tubing. Test each connection, each time. When removing tubing after sampling, it is normal to observe an indentation in the tubing where the nut clamped down on it.
