Overview

Meet the Ganivsor 357255 Lid O-Ring, a durable 2-pack replacement designed for popular Pentair and Sta-Rite pool and spa pumps. Crafted from Buna-N (nitrile rubber), this O-ring delivers a reliable seal around the pump lid, aiding in maintenance intervals while resisting routine pool chemicals and changing temperatures. The two-pack format provides a ready spare for future service needs, helping you stay prepared without scrambling for a replacement.

Why this matters

During routine maintenance or seasonal openings, a fresh lid O-ring can help preserve pressure balance and minimize seepage around the lid. The Buna-N material offers dependable flexibility and chemical resistance, contributing to a stable seal across common pool spa environments. While replacements cannot guarantee specific outcomes, many pool owners find that a fresh O-ring supports smoother operation and reduced annoyance from minor leaks.

  • Pentair model compatibility: 348021, 348022, 348023, 348024, 348025, 348026
  • Pentair model compatibility: 340036, 340037, 340038, 340039, 340040

  • Sta-Rite compatibility: SuperMax high pressure inground pumps
  • Sta-Rite compatibility: SuperFlo inground pumps

With regular service intervals, replacing the O-ring helps maintain seal integrity around the lid, reducing the risk of leaks that can impact pump performance. The inclusion of two O-rings provides flexibility for future maintenance, so you’re not stuck waiting for a replacement when it’s time to reseal.

  • Diameter and fit: Approximately 5-1/2" ID, 6" OD, 1/4" thick
  • Material: Buna-N (nitrile butadiene rubber) for durability and chemical resistance
  • Pack size: 2 O-Rings per pack

Tips for best results: inspect the groove for wear, clean the seating area, and apply a light compatible lubricant to the O-ring before seating the lid. Store spares in a cool, dry place to extend their readiness for service.
