Stomski Through Bolt O-Ring Installer with Sleeve
SKU #: STO-SR024
Installing O-rings on the through bolts for a 911 engine case often slices the rings on the threads of the bolt, leading to ripped seals at best, or a leaky engine at worst. Use this cap to protect the O-ring and to insure a factory quality seal. Precisely machined from quality brass.
