How to Read Our Part Numbers (Model Code Guide)

Follow the example below to identify the correct size and thread for your requirements:

Example Model: ZPL 08-01

1. Series Prefix (Shape)

• ZPL = Elbow (弯头)

• ZPC = Straight Connector (直通)

• Refer to the "Series Identification" list above for other shapes.

2. Tubing Diameter (PU/PE Hose O.D.)

• 04 = 4mm

• 06 = 6mm

• 08 = 8mm

• 10 = 10mm

• 12 = 12mm

3. Thread Size (BSPT / Metric)

• M5 = M5 x 0.8

• 01 = 1/8" (approx. 9.7mm)

• 02 = 1/4" (approx. 12.7mm)

• 03 = 3/8" (approx. 16mm)

• 04 = 1/2" (approx. 20mm)

⚠️ Important Note on Thread Sizes:

In the pneumatic industry, the thread code does not represent the actual measurement in inches. For example, 04 (1/2") thread measures approximately 20mm in diameter. Please verify your port size before ordering.；
