The Pentair 1-1/2 in. Thread Adaptor Kit (271094) is the OEM replacement threaded adapter pair for TR Series sand filters configured for installation without a valve.
⚠️ IMPORTANT: KIT LISTING — PAIR OF TWO ADAPTERS
This listing includes a pair of 1-1/2 in. threaded adapters — not a single adapter. One kit is required per filter unit.
This adapter kit provides the 1-1/2 in. threaded connections needed to plumb a TR Series sand filter directly into your system when no multiport or push-pull valve is used. The threaded adapters interface the filter tank's port openings to your existing 1-1/2 in. plumbing, allowing a clean, leak-resistant connection at both the inlet and outlet positions. If your filter setup omits the valve assembly entirely, this kit supplies the correct threaded fittings to complete the plumbing connection.

Pro Tip
This kit is specifically for valve-free installations — if your TR100C or TR140C is plumbed with a multiport or push-pull valve, you do not need this adapter kit. Before ordering, confirm your filter's plumbing configuration by checking whether the top port of your tank connects directly to supply and return lines without a valve body in between. If a valve is present, consult your filter's parts diagram for the correct valve-side fittings.
