Description

The Pentair 1.5″ Black Union Kit SKU 351157 is an OEM plumbing accessory that connects your Pentair SuperFlo or SuperMax pump to standard 1.5″ PVC lines. Its union design allows for fast disconnection without cutting pipe, and the included O‑ring adaptors help ensure a secure, leak‑resistant seal. Durable black PVC resists chemicals and UV exposure in outdoor pool environments. 

Pro Tip

Apply a small amount of pool‑safe lubricant to the O‑rings before assembly to improve seal life and ease of installation.
