Standard Inserts

Warning!Important Safety Information

Inserts

These inserts are part of our Standard Sealing System. Inserts of different sizes are needed when working with various stem sizes. The insert is easy to change, simply unscrew the 4 brass screws, change insert and secure screws. Inserts come in 5 different sizes (3/32”, 1/4”, 3/8”, 1/2” and grass slot 1/8” x 1/2”).

Your instrument might have a Compression Gland installed. This is a 1/4 inch adjustable hole that makes sealing a sample considerably easier and quicker. It works for most samples but not for bladed grass or samples larger than 1/4 inch. For these type samples use the Standard Insert and Gasket.

These Inserts DO NOT fit the Model 670.

All instruments now come standard with the Compression Gland Cover.

Do you have the old “Standard Sealing System”? Would you like to see a comparison and how easy it would be to convert it? Click here for a video comparison of the two systems.
