Description
Stainless Steel 3000# Forged Half Coupling - Grades 304L & 316L
Stainless Steel 3000# Forged Half Couplings are designed to provide a compact branch or equipment connection in high-strength stainless steel piping systems. Available in 304L and 316L stainless steel, these forged fittings are commonly used where a single threaded or socket weld connection is needed rather than a full-length coupling.
Forged stainless steel material conforms to ASME A182, fitting dimensions conform to ASME B16.11, and NPT threads conform to ASME B1.20.1. The product family is manufactured in an ISO 9001:2008 certified facility.

Half Coupling Design
A half coupling is a shorter coupling-style fitting designed where only one pipe connection is required. It is commonly used for branch takeoffs, vessel or equipment connections, and compact piping assemblies.
Compared with a full coupling, the half coupling uses a shorter body and is intended for a single-side connection rather than joining two pipe sections end-to-end.
3000# Forged Construction
These half couplings are manufactured from forged stainless steel conforming to ASME A182. Forged construction provides a durable fitting body intended for demanding threaded and socket weld applications.
Fitting dimensions conform to ASME B16.11 for applicable forged stainless steel piping systems.
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
Threaded & Socket Weld Standards
NPT Threaded Connections
- NPT threads conform to ASME B1.20.1
- Designed for compatible tapered pipe-thread connections
- Confirm thread size before assembly
- Use an appropriate thread-sealing method where required
Socket Weld Connections
- Socket weld fittings conform to ASME B16.11
- Designed for compatible welded piping systems
- Confirm pipe size and socket dimensions before welding
- Use appropriate welding procedures for the material and system
Full Coupling vs. Half Coupling
Half Coupling
- Shorter coupling body
- Designed for a single pipe connection
- Useful for branch and equipment connections
- Compact installation profile
Full Coupling
- Full-length coupling body
- Designed to connect pipe from both ends
- Commonly used to join two pipe sections in-line
- Different configuration from a half coupling

Frequently Asked Questions
What is a half coupling used for?
A half coupling provides a compact single-end pipe connection and is commonly used for branches, vessels, tanks, equipment, and instrument connections.
What pressure class are these half couplings?
These are 3000# forged stainless steel half couplings.
What stainless steel grades are available?
These half couplings are available in 304L and 316L stainless steel.
What is the difference between a half coupling and a full coupling?
A half coupling is shorter and designed for a single connection. A full coupling has a longer body and is generally used to connect two pipe sections from opposite ends.
