Description

Every hydraulic system and compressed air line on your farm has fittings that need to be sealed off, whether you’re winterizing equipment, doing repairs, or just keeping debris out of unused ports. This 1/8 inch female NPT black iron cap threads right onto male fittings to give you a secure seal that won’t back out under pressure.

What You’re Getting

Standard 1/8 inch female NPT threads that fit most common hydraulic and pneumatic fittings
Black iron construction that resists corrosion and handles high pressures
Tight seal that keeps fluids in and contaminants out
Easy to install and remove when you need access to the fitting

Built for Real Farm Work

These caps are perfect for sealing off hydraulic lines on tractors, loaders, and implements when you’re doing maintenance or storing equipment. You’ll also find them handy for air compressor lines, fuel system work, and anywhere you need to cap off a 1/8 inch male NPT fitting temporarily or permanently.

Made to Last

Black iron stands up to the oil, grease, and weather that farm equipment sees every day. The threads are cut clean and true, so you get a solid connection that won’t leak or work loose from vibration. These caps handle both high and low pressure applications without any trouble.

Good to Know

Hand-tighten first, then snug it down with a wrench—don’t overtighten or you might damage the threads. A little pipe dope or Teflon tape on the threads helps ensure a leak-free seal. Keep a few extras in your toolbox since you never know when you’ll need to cap off a line in a hurry.
