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.
