All three connector systems stay visible so you can compare tradeoffs even when one option is the primary recommendation.

Designed for both DIY buyers and professional installers.
Shows size-specific SKUs so users can move directly into product selection.
Keeps threaded fittings in the comparison even when they are not the primary recommendation.

Project inputs

Select the pipe size, installation location, and installer profile. The recommendation updates after submission and the comparison uses the selected size for each SKU.

Installation location

Access after installation matters because some connector systems are easier to service or rework later.

User type

The recommendation favors lower-risk systems for first-time users and more proven systems for experienced installers.

Pick your project details and submit to see the recommended connector and size-specific SKU links.

Connector selector FAQ

All three connector systems stay visible so you can compare tradeoffs even when one option is the primary recommendation.

Why is threaded not usually the primary recommendation?

Threaded fittings stay useful when space and budget matter, but they also carry more leak risk when installation technique is inconsistent. That makes them harder to recommend as the safest default for mixed audiences.

Can I mix connector types in one project?

Yes, many installers mix systems when different areas have different access, service, or speed requirements. The key is to stay within the same SP system compatibility rules and product instructions.

Are all three compatible with the same SP pipe sizes?

For this tool, yes. The selected sizes from 16 mm through 50 mm all map to matching SKUs in the three connector families shown here.
