Frequently Asked Questions (FAQ)

1. What's the difference between ISO and SAE cross fittings?

ISO fittings follow international metric standards (ISO 4144), while SAE uses imperial measurements. Our fittings meet both specifications.

2. How to prevent thread galling during installation?

✔ Use proper thread lubricant
✔ Avoid overtightening (recommended torque values provided)
✔ Consider anti-gall compound for stainless steel

3. Maximum pulsation pressure rating?

Rated for 6,000 PSI static, 4,500 PSI dynamic with pulsation.

4. Available material options?

Standard: 304/316 SS
Optional: Carbon steel, brass, alloy 20

5. Chemical compatibility guidance?

Detailed chemical resistance charts available for all materials.

6. Lead time for custom orders?

2-3 weeks for standard customizations (non-stock sizes/materials).

7. Pressure testing certification?
