Frequently Asked Questions

Q: What is the difference between NPT and GHT threads?

A: NPT (National Pipe Thread) is a U.S. standard for tapered pipe threads used in plumbing and pressurized systems. GHT (Garden Hose Thread) is a straight thread standard used for garden hose connections in North America. This adapter bridges both standards, allowing you to connect NPT-threaded pipes or fittings to GHT-threaded hoses or devices.

Q: Do I need thread seal tape to install these adapters?

A: Yes. It is recommended to wrap PTFE (polytetrafluoroethylene) thread seal tape around both threaded ends before installation to ensure a watertight, leak-free seal.

Q: Are these PVC pipe adapters safe for drinking water applications?

A: These adapters are made from non-toxic PVC and are suitable for cold water supply pipelines. However, they are primarily designed for irrigation, sprinkler systems, swimming pools, and outdoor cold water lines. For confirmed potable water use, please verify local plumbing codes and ensure compliance with your region's standards.

Q: What is the maximum pressure these adapters can handle?

A: These adapters are rated for pressures up to 850 kPa, making them suitable for standard residential irrigation and water supply applications.
