Technical Features
- Malleable iron construction provides high tensile strength and resistance to impact, suitable for demanding piping environments.
- 300 PSI pressure rating supports high-pressure piping installations where standard low-pressure fittings are insufficient.
- Wide operating temperature range of -4 to 572F compatible with steam, hot water, and cold-weather piping applications.
- SCH 40 schedule rating ensures compatibility with standard Schedule 40 threaded pipe systems for consistent, leak-resistant connections.
- MIP x FIP threaded connection enables direct, tool-secured assembly between male and female threaded pipe ends without additional adapters.
- 0.64 in. hex size allows standard wrench engagement for secure installation and removal without slippage.
- Compact 0.58 in. length minimizes space requirements in tight pipe runs while maintaining full thread engagement.
- Black finish standard black iron coating consistent with black iron pipe systems used in gas and industrial plumbing lines.
Applications
- Reducing pipe thread size from 1/4 in. to 1/8 in. in threaded piping assemblies
- Natural gas and propane distribution piping where black iron fittings are specified
- Steam and hot water piping systems operating within the rated temperature range
- Industrial and commercial plumbing installations requiring SCH 40 rated components
- Compressed air and hydraulic lines operating at or below 300 PSI
