Crimped vs Push-On Hydraulic Fittings: What’s the Difference?
Crimped fittings are permanently swaged onto the hose with a hydraulic press, giving a stronger, more reliable seal at high pressure. Push-on (or field-attachable) fittings screw on by hand and suit lower-pressure or temporary repairs.
How a Crimped Fitting Is Made
A crimping machine compresses a metal ferrule around the hose and fitting under high force, permanently deforming it to grip the hose reinforcement. Done correctly, it’s one of the strongest connections you can make in a hydraulic circuit.
Where Push-On Fittings Make Sense
Field-attachable fittings can be screwed onto a hose without a crimping machine, which is useful for low-pressure lines or genuine emergencies where getting a truck moving matters more than a perfect long-term fix.
Why It Matters for Truck Hydraulics
Tipper, crane and mine-support systems typically run at pressures where a properly crimped assembly is the safer, longer-lasting choice — a push-on fitting under sustained high pressure is more prone to working loose over time.
Matching the Fitting to the System
The right choice also depends on hose type and working pressure, not just convenience. If you’re not sure what your system needs, bring in the old assembly and we’ll match it or advise the correct current equivalent.
