1. Fluid Type

Check the type of fluid used in the application, such as air, water, oil, or gases.

Examples:

• Air Applications: Use UNR Series couplings

• Water Applications: Use YSP, NSP Series

Tip: Choose the appropriate body and seal materials depending on the fluid type to ensure compatibility and long-lasting performance.

2. Fluid Pressure

Couplings and pipe clamps offer varying levels of pressure resistance based on application requirements.

Tip: Use couplings rated for the maximum pressure in your system.

Example:

• Pressure rating: 20.6 MPa (210 kgf/cm²) for the SPH-050 Series

3. Fluid Temperature

The operating temperature of the fluid plays a crucial role in choosing the right sealing material.

Tip: Select sealing materials suitable for high or low temperature ranges.

Example:

• Nitrile rubber is suitable for fluids at temperatures ranging from -20°C to +80°C.

4. Size, Connection Type, Valve Structure, and Body Material

• Size: Choose a size that matches your system, typically 1/8" to 2" (Diameter: 3.18 mm to 31.75 mm).

• Connection Type: Available in male/female thread, hose nipple, nut, and plug.

• Valve Structure: Select from various types such as double shut-off, single shut-off, or straight-through types.

• Body Material: Choose from steel, brass, or stainless steel to meet your durability or corrosion resistance needs.

5. Working Environment

Evaluate the conditions in which the coupling will be used — including temperature, dust, vibration, and chemical exposure.

Tip: Choose couplings designed to withstand harsh environments and maintain safety and durability.

Example: Avoid using standard couplings in dusty or corrosive environments — choose reinforced or sealed types instead.

6. Clamped Work Pieces Detail

When using couplings for clamping workpieces, ensure that you:

• Use custom-made pipe clamps if required.

• Review workpiece drawings.

• Confirm original work position settings.
