Earl's AT993301 - Earl's Ano-Tuff Hex and Allen Head NPT Pipe Plugs
Earl's Ano-Tuff Hex and Allen Head NPT Pipe Plugs
Earl's Ano-Tuff Hex and Allen Head NPT Plugs are precision machined from aluminum with a distinctive, bright dip black, military spec hard anodizing. This recently developed hard anodizing process adds superior wear and corrosion resistance to aluminum at a reasonable price. The Ano-Tuff coating penetrates the aluminum to create a surface that lasts twice as long as traditional anodizing. Available in a variety of sizes, these plugs are excellent for sealing extra ports on intake manifolds, cylinder heads, and fuel pressure regulators. Made in the USA!
