Description

A cracked or worn coupling can lead to leaks, air intrusion, and reduced pump efficiency. The Pentair 274400Z 2-inch coupling is an OEM replacement designed to restore a secure and properly aligned connection in compatible pump plumbing systems.

This durability-focused component is built to withstand pressure, vibration, and chemical exposure while maintaining a tight seal. It allows for fast repair without cutting plumbing, making it a reliable solution for both service techs and homeowners.

Pro Tip

When servicing a union connection, inspect the O-ring and union nut at the same time. Replacing all sealing components together helps prevent repeat leaks.

Installation Tips

Shut off pump and relieve system pressure before servicing. Ensure threads are clean and aligned, seat the O-ring properly, and avoid overtightening to prevent damage.
