COMP Cams 11/32" Positive‑Stop PTFE seal fits 11/32" valve stems and .530" guides with a .630" seal diameter to allow use with double springs. These PTFE positive‑stop seals keep oil from entering the combustion chamber through valve guide clearance while providing the additional clearance some dual‑spring installations require, offering a practical option when umbrella seals are too large.
