When you’re dealing with hydraulic systems on your tractor or equipment, having reliable fittings can make the difference between a smooth day in the field and being stuck with a busted hose when you need your machine most. This 4S series crimp fitting gives you a solid, leak-free connection between your 1-inch hydraulic hose and any component with 1-inch NPTF female threads.
What You’re Getting
- Male NPTF threads that create a tight, drip-free seal without thread sealant
- Straight rigid design handles high pressures without flexing or loosening
- Professional crimp construction locks onto your hose permanently – no clamps to work loose
- One-inch thread size matches common hydraulic valves, pumps, and cylinders
- 4S series quality built to handle the pressure and vibration of agricultural equipment
Built for Real Farm Work
Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. This fitting is designed for tractors, loaders, balers, and other hydraulic equipment where you need a permanent connection that won’t fail under pressure. Whether you’re running hydraulic motors on hay equipment or powering cylinders on your three-point hitch, this fitting handles the job without backing out or leaking.
Made to Last
They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. The NPTF thread design creates a mechanical seal that gets tighter under pressure, so vibration actually helps keep things sealed rather than working connections loose like some other thread types.
Installation Notes
This is a crimp-on fitting that requires proper crimping equipment – don’t try to install it with hose clamps or other makeshift methods. The crimp creates a permanent connection that’s actually stronger than the hose itself. Thread the fitting hand-tight into your component, then snug it up with a wrench – NPTF threads don’t need pipe dope or Teflon tape to seal properly.
