About This Item

The Pentair Liner Sealing Ring (79200100) is the OEM replacement 8-hole sealing ring for Pentair Large Stainless Steel pool lighting niches, designed to form a watertight seal between the pool liner and the niche housing.

IMPORTANT: POOL LIGHTING SAFETY
Pool lighting components operate in wet environments. Installation must comply with NEC Article 680 and be performed by a licensed electrician.

This sealing ring seats against the face of the large stainless steel niche and compresses against the pool liner to prevent water intrusion into the niche cavity. The 8-hole pattern aligns with the niche's mounting flange. A missing, cracked, or deteriorated sealing ring will allow water to bypass the liner seal, potentially compromising the niche installation and surrounding structure.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

Before ordering, count the holes in your existing sealing ring — Pentair niches are available in both 8-hole and other configurations, and rings are not interchangeable between them. Also confirm you have the large niche size, as a different sealing ring is required for small niches. The mounting screws are not included with this ring; the compatible Pentair 98202600 1/4-20 × 1" Phillips flat head sealing screws are sold separately. As with any niche service, have a licensed electrician perform the work to maintain compliance with NEC Article 680.
