Description
When you’re working on hydraulic systems, you know that loose ends and open ports spell trouble. Dirt, moisture, and debris love nothing more than finding their way into hydraulic lines, and that’s where this handy 3/8 inch FNPT galvanized cap comes to the rescue. Whether you’re capping off unused ports during system repairs or sealing lines for winter storage, this little fitting keeps your hydraulic system clean and protected.
What You’re Getting
- 3/8 inch female NPT threads for a secure, leak-proof connection
- Galvanized coating protects against rust and corrosion in wet conditions
- Solid construction that won’t crack under pressure like plastic caps
- Direct threading design – no gaskets or seals to lose or replace
Built for Real Farm Work
This cap fits any 3/8 inch male NPT hydraulic fitting, making it perfect for tractors, loaders, combines, and hydraulic implements. You’ll find 3/8 inch fittings on auxiliary hydraulic lines, hydraulic motors, and various system components where smaller flow rates are needed. It’s also handy for shop work when you need to cap off hydraulic test ports or unused connections on manifolds and valves.
Made to Last
The galvanized finish means this cap can handle the wet, muddy conditions that come with farm work without rusting out. Unlike plastic caps that get brittle and crack, this steel construction holds up to the bumps and knocks of daily use. The precision threads ensure a tight seal that won’t back out from vibration.
Good to Know
These caps thread on by hand initially, then snug them down with a wrench for a proper seal. A light coating of hydraulic fluid on the threads helps prevent seizing and makes removal easier later. Keep a few extras in your toolbox – you’ll be surprised how often you reach for them during hydraulic repairs and system modifications.
