Black Iron Cap for 1 Inch FNPT Threads

Description

Whether you’re capping off a hydraulic test port after repairs or sealing an unused opening in your tractor’s manifold, this black iron cap gets the job done right. Nothing’s more frustrating than a slow leak dripping hydraulic fluid all over your shop floor, and a quality cap like this one keeps everything sealed up tight where it belongs.

What You’re Getting

• Solid black iron construction that won’t crack under pressure like plastic fittings
• 1-inch female NPT threads that fit standard hydraulic and plumbing applications
• Durable material that handles temperature swings from winter shop work to summer field repairs
• Threads stay tight even after multiple removals for maintenance work

Built for Real Farm Work

This cap works great for sealing hydraulic manifolds on tractors, capping unused ports on air compressors, or blocking off fuel system test ports during repairs. You’ll find it handy on everything from loader hydraulics to implement plumbing, anywhere you need to close off a 1-inch NPT female opening securely.

Made to Last

Black iron fittings are the workhorse of farm plumbing because they don’t crack under pressure like plastic can. The material handles temperature swings from winter shop work to hot summer field repairs, and the threads stay tight even after multiple removals.

Installation Notes

Use a little pipe thread sealant or Teflon tape for the best seal, especially on hydraulic applications. The hex head gives you plenty of grip for hand-tightening plus a quarter turn with a wrench—that’s usually all you need for a solid seal without overtightening.
