Maintenance for Compression Gland Cover

Maintaining the Compression Gland Cover is quite simple. Keep the O-ring around the Compression Gland Insert clean and lubricated with petroleum jelly. Occasionally unscrew the compression screw and take out the small metal disc and Compression Gland Gasket inside for cleaning. We recommend lubricating the compression screw threads with a Teflon based lubricant such as TRI-FLOW or other lubricant to maintain the threads and ensure easy operation. Keeping these threads clean is important for ensuring operability of the cover. Clean the Compression Gland Gasket with ARMOR ALL or other similar cleaner. Over time the compression gland gasket will become worn, a replacement has been supplied for your convenience. If additional gaskets are needed, you may purchase them directly from PMS Instrument Company.
