COMP Cams Positive‑Stop PTFE valve seal for 11/32" valves fits applications with .530" OD guides and a .630" seal diameter, offering tighter clearance for dual‑spring use. The smaller diameter compared with umbrella seals allows use with double springs while maintaining control of oil migration past the valve guide, making it useful in setups where spring packs reduce available clearance.
