Description
When you’re running heavy hydraulics on your tractor—whether it’s a loader, backhoe attachment, or high-flow implements—you need fittings that can handle the pressure without leaking or failing. This 4S series crimp fitting gives you that rock-solid connection between your 1-1/4 inch hydraulic hose and male JIC threads. It’s built for the kind of pressure and punishment that comes with real farm work.
What You’re Getting
- Straight rigid design that won’t bend or flex under pressure—perfect for high-flow applications
- Male JIC threads (1-5/8 inch x 12) that create a metal-to-metal seal for leak-free operation
- Professional crimp-on connection that won’t blow off like clamp-style fittings can
- Heavy-duty construction designed for the high pressures of modern hydraulic systems
- Direct replacement that works with standard hydraulic hose and crimping equipment
Built for Real Farm Work
This fitting is sized for the bigger hydraulic lines you’ll find on larger tractors and heavy implements. The 1-1/4 inch hose size handles the high flow rates needed for loaders, hay equipment, and other hydraulically-intensive attachments. JIC fittings are the standard for agricultural hydraulics because they seal reliably even when things get dirty and rough.
Made to Last
The fitting body is engineered to handle hydraulic system pressures without cracking or deforming. Quality construction means this fitting keeps sealing properly through temperature swings, vibration, and the inevitable bumps that come with field work.
Good to Know
Always use proper thread sealant on hydraulic fittings and clean both surfaces before connecting. Don’t over-tighten as this can damage threads—a snug fit with proper sealant is what you’re after. This fitting requires professional crimping equipment to attach properly to the hose.
