Frequently asked questions

How do I choose the right connection?
Match the same nominal pipe size at both ends. For two different pipe sizes, use the appropriate reducing coupling.
Where are the dimensions and weight?
Use the manufacturer table for the selected nominal size. Dimensions and unit weight vary by size; the image is a product-family reference.
Can I use this for any fluid or service?
Confirm material compatibility, thread arrangement, service conditions and the applicable manufacturer rating before selecting the fitting.
Does Class 150 mean 150 PSI in every application?
No. Pressure class is not one universal working-pressure limit. Allowable pressure depends on temperature, size, material and service; use the applicable manufacturer rating.

Before you order

Match the same nominal pipe size at both ends. For two different pipe sizes, use the appropriate reducing coupling. Confirm the complete size selection, thread compatibility, operating temperature and required service rating.
