With a 300 psi pressure rating, it’s designed to handle potable water lines, irrigation runs, and industrial piping projects that require durable, leak-resistant performance.
Key features that matter in real-world installs:
- Lead-free construction ensures safe potable water use and aligns with plumbing codes that require low lead content.
- 1 in. MPT thread on the end(s) provides compatibility with standard 1 in. female fittings and adapters.
- 5-inch overall length offers extra reach and easier alignment when routing piping around obstacles.
- Stainless steel composition delivers excellent corrosion resistance and long service life in wet, humid, or outdoor conditions.
- Bagged packaging supports organized storage on the job site or in warehouses.
- Maximum pressure rating of 300 psi makes it suitable for water and select gas or air piping applications where code permits.
Practical applications
- Extending a run of water piping from a shut-off valve to a faucet, appliance, or fixture with compatible female connections.
- Repairs or retrofits in existing stainless or mixed-material lines that require a robust, corrosion-resistant connector.
- Outdoor or utility installations where moisture exposure is common, leveraging the nipple’s stainless steel durability.
Installation tips for best results
- Apply a compatible sealant or PTFE tape rated for stainless steel on male threads; avoid overtightening to prevent damage.
- Perform a leak test after assembly by gradually pressurizing the line and inspecting joints for drips or seepage.
- Ensure proper alignment before final tightening to minimize thread wear and maintain a reliable seal over time.
