External Thread Connector FAQ
What is the difference between NPT and BSPP thread types in external thread connectors?
NPT (National Pipe Thread) is a tapered thread that creates a seal through thread deformation, while BSPP (British Standard Pipe Parallel) has parallel threads and requires a sealing washer. NPT is common in North America, while BSPP is standard in Europe and Asia. Our external thread connectors are available in both types to accommodate different regional requirements.
How do I prevent leaks when using external thread connectors?
For NPT external thread connectors, use thread sealant tape or pipe dope on male threads. For BSPP connectors, ensure proper washer installation. Always hand-tighten before using a wrench, and avoid over-tightening which can damage threads. Our external thread connectors feature precision-cut threads that minimize leak potential when installed correctly.
What maintenance do external thread connectors require?
Regularly inspect external thread connectors for signs of wear, corrosion, or damage. Clean threads periodically and reapply sealant if necessary. For stainless steel external thread connectors in harsh environments, we recommend annual inspections. Brass connectors may require more frequent checks in corrosive applications.
Installation Guidelines
- Clean both male and female threads thoroughly before installation
- Apply appropriate thread sealant (for NPT) or install washer (for BSPP)
- Hand-tighten the external thread connector until snug
- Use a wrench to tighten an additional 1-2 turns (do not over-tighten)
- Pressure test the system before full operation
