Square Head Design
The square head provides a defined wrenching surface that helps make installation and removal straightforward using an appropriate wrench.
This design is useful where a threaded opening needs to be closed while still allowing future access for maintenance, inspection, or system modification.
Threaded Pipe Plug Connection
The plug uses male NPT threads for installation into a compatible female-threaded opening. NPT threads conform to ASME B1.20.1.
Use an appropriate thread sealant for the piping media and application, and verify thread size and compatibility before installation.
3000# Forged Construction
These pipe plugs are manufactured from forged stainless steel conforming to ASME A182. Forged construction provides a durable fitting body suitable for demanding threaded piping applications.
Forged fitting dimensions conform to ASME B16.11.
304L vs. 316L Stainless Steel
304L Stainless Steel
- General-purpose stainless steel grade
- Strong corrosion resistance for many industrial applications
- Commonly used in water and process piping
- Low-carbon stainless grade
316L Stainless Steel
- Enhanced corrosion resistance for more demanding environments
- Commonly selected for marine and chloride-exposed applications
- Useful in many chemical and process piping systems
- Low-carbon stainless grade
