ALAN offers several types of gaskets: Basic rings, with a range of I.D.-O.D.; Gasket strips, a long rectangular piece uncut and coiled; and Ring Sets, comprising concentric gasket rings, cut but not separated.
All gaskets are GSA-2 sided, 1/8" thick 2# polyethylene foam.
ALAN's gaskets can be removed and replaced without tearing within five minutes of initial placement, if need be - a feature not found on other gaskets - yet they remain just as securely attached once set.
