Choose 304 or 316 Stainless Steel
304 Stainless Steel
The SSP4CPLH series is manufactured from 304 stainless steel and is available in nominal sizes from 1/8" through 4". Select 304 stainless steel where that material grade meets the requirements of the piping system or fabrication application.
316 Stainless Steel
The SSP6CPLH series provides the half-coupling configuration in 316 stainless steel. Select 316 stainless steel when that material grade is specified or required for the application.
Half Coupling Configuration
Female NPT Connection
- Female NPT threaded connection
- Accepts a compatible male NPT component
- Compact half-coupling body
- Available in multiple nominal pipe sizes
- 304 and 316 stainless steel options
Half Coupling vs. Full Coupling
A half coupling is a shorter fitting configuration than a full coupling and provides a single female threaded connection. Confirm that a half coupling rather than a full female NPT x female NPT coupling is required before ordering.

Frequently Asked Questions
What is a half coupling?
A half coupling is a compact coupling configuration with a female threaded connection. It is shorter than a full coupling and is used where a single threaded connection point is required.
Are these half couplings available in both 304 and 316 stainless steel?
Yes. This listing includes both 304 and 316 stainless steel half couplings. Available nominal sizes differ slightly between the two material grades.
What is the difference between SSP4CPLH and SSP6CPLH?
SSP4CPLH identifies the 304 stainless steel series, while SSP6CPLH identifies the 316 stainless steel series.
What connection type does the half coupling use?
These half couplings have a female NPT threaded connection.
What pressure class are these fittings?
These stainless steel threaded half couplings are identified as 150 lb class fittings.
What sizes are available?
The 304 stainless steel series is available from 1/8" through 4", including 3/8" and 2-1/2". The provided 316 stainless steel series includes 1/8", 1/4", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 3", and 4".
Is this the same as a full coupling?
No. This listing is specifically for half couplings. Full couplings are a separate product family.
How do I select the correct variant?
Select the nominal pipe size required for the connection and then select either 304 or 316 stainless steel according to the material requirements of the application.
