About This Item
OEM Threaded Adapter for Pentair HiFlow Multiport Valves
The Pentair 274651Z is the OEM replacement threaded adapter for HiFlow 1-1/2" and 2" Top Mount and Side Mount Multiport Valves. If your valve's plumbing connection is leaking or the adapter threads are damaged, this is the correct factory replacement to restore a secure, watertight connection. This is the adapter specificallt for the 1-1/2" threaded (as opposed to 1-1/2" slip or 2" threaded).
What It Does
This PVC threaded adapter connects the multiport valve body to the pool's return or waste plumbing. A cracked or stripped adapter allows water to bypass the valve seal, reducing filtration efficiency and potentially causing water loss. Replacing it with the OEM part restores the correct thread engagement and sealing geometry specified for these valve models.

Pro Tip
Before ordering, confirm whether your valve uses a 1-1/2" or 2" adapter port — the HiFlow line spans both sizes and the adapters are not interchangeable. Check the port size stamped on your existing adapter or reference the model number on your valve's label against the models listed above.
