About This Item
The Pentair Union Kit 2 in. I.D. (Part #270100) is the OEM replacement union kit for Pentair FNS Plus D.E., Quad D.E., and Clean & Clear Plus cartridge filters. This black, 2-inch internal diameter kit is used specifically on filter installations without a valve assembly, providing a direct plumbing connection between the filter and the return line.
IMPORTANT: KIT CONTENTS — SOLD AS A SET
Part #270100 is sold as a complete union kit. One kit is included per order. Confirm the quantity required for your installation before ordering.
IMPORTANT: NO-VALVE ASSEMBLY APPLICATIONS ONLY
This union kit is designed for Quad D.E. filter installations where no valve assembly is present. The valve assembly must be purchased separately if required. For FNS Plus filters, fitment is optional — confirm your plumbing configuration before ordering.
The 270100 union kit provides a secure 2-inch I.D. union connection at the filter's plumbing port in no-valve configurations. A properly functioning union allows the filter to be disconnected from the plumbing system for service without cutting pipe. Replacing a worn or cracked union kit restores a watertight, serviceable connection at the filter port.

Poolaroo Pro Tip
When replacing the union kit on a Quad D.E. filter in a no-valve configuration, inspect both union faces and the surrounding plumbing connections for hairline cracks or surface degradation before reassembly. On FNS Plus filters, this union kit is listed as optional — it is typically added when the filter port is plumbed directly without a multiport valve and a serviceable disconnect point is needed. Confirm your filter's plumbing configuration against the equipment manual before ordering.
