Pentair | 357255Z | Strainer Cover O-Ring | Buna-N 70 | #2-357 Replacement Seal
The Pentair 357255Z Strainer Cover O-Ring is a replacement sealing component designed for pump strainer cover applications requiring a Buna-N 70 compound and #2-357 size. This O-ring helps create a watertight seal between the strainer lid and housing, reducing air intrusion and water leakage while supporting proper priming and reliable circulation performance.
Key Features
• Replacement strainer cover O-ring designed for pump lid sealing applications using size #2-357.
• Manufactured from Buna-N 70 material for dependable sealing performance in pool equipment environments.
• Helps create a watertight seal between the strainer cover and pump housing.
• Reduces the risk of air entering the pump system and affecting priming performance.
• Supports stable circulation and efficient hydraulic operation during normal use.
• Ideal for replacing worn, flattened, cracked, or chemically degraded O-rings during maintenance.
Product Overview
The Pentair 357255Z Strainer Cover O-Ring is an essential service part used to maintain a secure seal at the pump strainer cover. Proper sealing at the lid is critical for keeping the pump primed, preventing suction-side air leaks, and supporting consistent water movement through the circulation and filtration system. When the strainer cover O-ring is in good condition, it helps the pump operate more efficiently and reduces the chance of performance issues caused by air intrusion or water seepage.
Constructed from Buna-N 70 material, this replacement O-ring is suited for demanding pool equipment service conditions and is identified by the #2-357 size for precise fitment where required. Over time, strainer lid O-rings can become compressed, brittle, or damaged from repeated removal, chemical exposure, and temperature changes. Replacing a compromised seal with the 357255Z helps restore proper lid sealing, improve pump reliability, and support long-term performance during routine equipment maintenance and service.
