Hydraulic Fittings Strict Quality Control

As one of the top hydraulic fittings Manufacturers, Quality is not only in our products but also in every service and management process we provide. Our hydraulic fittings are present in each step of the manufacturing process.

  1. Check material surface, visual, hardness, and size
  2. First hydraulic fittings check through drawing, thread(ed) gauge, CMM & 3D Precision Measurement to make sure it is Precision
  3. Mass hydraulic fittings check, inspect the threads/10 pieces, drawing sizes/15 pieces. If disqualified is found, the entire lot will be rejected and immediately returned to the non-conforming department.
  4. Final inspection, 15-20% random check Critical dimensions and angles with calipers and Angle instrument. Use a thread gauge to check the thread.
  5. Package and label:  (1)Male and female hydraulic fittings have plastic caps and plugs.   (2) A foam film separates each layer of hydraulic fittings to prevent bumping.  (3) Make labels on each plastic bag and carton as per your requirements.
  1. All inspection equipment is calibrated regularly to ensure the accuracy and consistency of measurements.

Hydraulic Fittings Application

Hydraulic hoses and hydraulic fittings are widely used in different hydraulic industries. Hydraulic fitting connects hydraulic hoses to parts such as pumps, pipes, and hydraulic cylinders in a hydraulic system.

Different hydraulic fittings allow fluid to flow, change direction, steer or mix. These hydraulic fittings create a tight seal and prevent leakage in the application. These hose fittings are used in a wide range of hydraulic power applications, including piping, robotics, assembly lines and heavy equipment

Use the right hydraulic fittings type and thread for the equipment

  • Reduce the number of hydraulic fittingsused in hydraulic systems
  • Tighten hydraulic adapters and hydraulic hose fittings correctly
  • Reducevibration
  • Perform preventive and corrective maintenance

As per your experience to determine the thread is tapered or parallel, then use the tools ID/OD calipers and Thread pitch gauge to check Specific threads and dimensions.

It’s not advisable. Hydraulic fittings are mechanically sealed by an o-ring,metal on metal seal or bonded washer, no need teflon tape. It can enter the system and clog or cause tight tolerance problems when use teflon tape not properly.

Use Topa hose crimping machine, it is easier to crimp hose assembly, Measure hydraulic hose and choose right hydraulic fitting, adjust the Crimper Setting,select The Die size, then start machine, you can crimp

There are two ways to determine the thread size

  • For pipe threads, measurethe actual outside diameter minus ¼” and rounding up
  • For non-pipe threads, measurethe outside diameter (major diameter) with calipers

Hydraulic fittings are mechanically sealed by O-rings, metal-to-metal seals or adhesive gaskets

Use two wrenches and force. When you need to tighten a hydraulic hose fitting, the movable jaws of the wrench are pushed against the body of the wrench; do not hold your wrench in the wrong way. And always turn the movable wrench to the movable hawthorn.

Then tighten the hydraulic hose fitting as much as you can until you feel it is hard to turn the wrench. The hydraulic hose will be well seized by the hydraulic hose coupling.

It is much softer than steel and brass has a much lower melting point. For this reason, brass fittings are mainly used in cool, low-pressure systems. However, brass does not spark. For this reason, brass fittings are widely used in automotive applications and fuel lines.

  1. Determine if the hydraulic fittings thread type, is tapered or parallel
  2. Identifyfitting ends and port hydraulic fittings
  3. Identifythe sealing method
  4. Determine the pitch and size

We need tools Wrench, Hose cutter,Lubricant and Bench vise, first cut hose, a straight clean cut is important. Screw the hydraulic ferrule onto the hose, rotate it until the inside of the hose bottoms out. Secure the ferrule in a vise, lubricate the stem and the inside of the hydraulic hose with some hydraulic fluid, and then start turning the stem. Push and turn until the threads engage.
