Hex Head Design
The hex head provides multiple wrench flats for positive tool engagement during installation and removal.
This design is useful where a threaded opening needs to be securely closed while still allowing future access for inspection, maintenance, or system modification.
Male NPT Threaded Connection
The plug uses male NPT threads for installation into a compatible female-threaded fitting, valve, port, or equipment connection.
NPT threads conform to ASME B1.20.1. Use an appropriate thread sealant for the piping media and application and confirm thread size 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
Hex Head vs. Square Head Pipe Plugs
Hex Head Plug
- Six-sided external wrenching surface
- Provides multiple wrench engagement positions
- Designed for threaded opening closure
- Useful where conventional wrench access is preferred
Square Head Plug
- Four-sided external wrenching surface
- Also designed for threaded opening closure
- Different head geometry from the hex style
- Selection may depend on installation preference or available clearance
