What Is an SP112 Threaded Cap?
The Charman Inc SP112 threaded cap is a closed-end stainless steel fitting with a female threaded connection. It installs over a compatible male-threaded pipe or fitting to terminate the end of a piping run.
Threaded caps are commonly used at permanent terminations, temporary service points, future expansion locations, and equipment connections where a removable threaded closure is preferred.
Why Choose a 316 Stainless Steel SP112 Cap?
316 Stainless Steel Construction
- Provides strong general corrosion resistance
- Useful in many industrial and process environments
- Suitable where 316 stainless steel piping components are specified
- Durable construction for threaded piping systems
- Well suited for utility, mechanical, process, and equipment applications
Simple Threaded Termination
- Female threaded connection installs over compatible male threads
- Provides a compact end-of-line closure
- Can be removed later when system access is required
- No welding required for normal threaded assembly
- Useful for permanent or serviceable piping terminations
Common Applications
Industrial & Process Piping
- Process piping systems
- Industrial utility piping
- Equipment connections
- Threaded stainless steel assemblies
- End-of-line piping terminations
Commercial & Mechanical Systems
- Commercial plumbing
- Mechanical piping systems
- Maintenance and repair installations
- Temporary or future connection points
- Equipment and manifold assemblies
Cap vs. Plug
A threaded cap has a female threaded connection and installs over a compatible male-threaded component. A threaded plug uses a male threaded connection and installs into a compatible female-threaded opening.
Select the cap configuration when the piping or fitting being closed has an external male thread.
Where an SP112 Threaded Cap Makes Sense
- Closing the end of a threaded piping run
- Terminating an unused male-threaded connection
- Providing a removable closure for future expansion
- Protecting an unused threaded connection during service
- Closing equipment or manifold connections
- Industrial process and utility piping
- Mechanical and commercial piping systems
- Maintenance, repair, and retrofit installations
Ask Willy: Need Stainless Steel Fitting Information?
Review the Charman Inc stainless steel fittings specification sheet for product and dimensional information on SP112 threaded fittings, or use the complete stainless steel fittings catalog to compare available fitting styles, configurations, and sizes before ordering.
Installation & Selection Guidance
- Confirm the required nominal pipe size before ordering.
- Verify that the mating component has a compatible male NPT connection.
- Confirm that a threaded cap is appropriate for the piping layout.
- Confirm that 316 stainless steel is compatible with the intended service.
- Inspect fitting and mating threads for damage or contamination before assembly.
- Use a thread-sealing method appropriate for the system media, pressure, temperature, and application.
- Begin threaded assembly carefully to reduce the risk of cross-threading.
- Tighten the cap using appropriate tools and accepted threaded-piping practices.
- Avoid excessive tightening that could damage the cap or mating threads.
- Confirm system pressure and temperature requirements before installation.
- Pressure-test completed piping assemblies where required.
- Installation should be completed by qualified personnel and in accordance with applicable codes and specifications.
Product Selection Considerations
Nominal Pipe Size
Select the SP112 cap based on the nominal pipe size of the male-threaded component being closed. Available sizes range from 1/4" through 2".
Thread Configuration
Choose a cap when the mating connection has an external male thread. A threaded plug is used instead when the opening being closed has an internal female thread.
