Connecting Nipple (for Parallel Pipe Thread and Metric Thread)

Specifications

How to choose Nipples

Points to check when selecting, with the values for this product (Connecting Nipple (for Parallel Pipe Thread and Metric Thread)).

1. 1. Match thread standard and nominal size at both ends

   Check the thread standard (G parallel, metric, NPT taper, etc.) and nominal size of both the connected equipment and the hose. Pitch must match exactly, such as M16x1,5. Parallel and taper threads are not interchangeable, so if conversion is needed, select the fitting by its end-to-end combination.

2. 2. Select a rating above the system's maximum pressure

   This product: Maximum Working Pressure 100～400 MPa

   The listed products have maximum working pressures from 100 to 400 MPa, and ratings vary by thread standard even for the same application. Determine the system's maximum pressure, including the pump's maximum discharge pressure and surge pressure, and select a nipple rated above it. The lowest rating among the fittings in the circuit sets the upper limit for the whole system.

3. 3. Confirm material suitable for pressure and fluid

   High-strength steel is common for high-pressure hydraulic use. Check corrosion resistance to the working fluid and compatibility with the mating component material. Review the applicable fluid and surface treatment items to confirm there is no risk of galvanic corrosion from dissimilar metal contact or incompatibility with the fluid.

4. 4. Check overall length for routing and interference

   The overall length of the nipple affects the distance between equipment and the routing of tools and hoses. Using the exposed length after subtracting thread engagement depth, check on the drawing for interference with surrounding parts and tightening tools. Note that an excessively long nipple is more susceptible to bending loads.

5. 5. Confirm wrench size and tightening torque

   The listed products have wrench sizes of 22 to 32 mm. Confirm the tool size and workspace required for tightening in advance. Where a recommended tightening torque is specified (for example, 45 N·m), controlling it with a torque wrench helps prevent leaks from under-tightening and damage to threads or seating faces from over-tightening.

6. 6. Verify operating temperature and fluid compatibility

   Confirm that the type of hydraulic oil and the fluid temperature fall within the product's operating temperature range and applicable fluids. If a sealing material is used together, judge its temperature resistance and oil resistance as well.
