5pcs 151122 O-Ring for Pentek Pentair Water Big Blue Housings
Design & Build Quality
The 151122 O-rings are built with precision to fit exactly into Pentek and Pentair Big Blue filter housings. Many users mention the easy installation due to the perfect size match. A user review notes, “These O-rings fit perfectly, and after a little silicone lubricant, the seal is tight with no leaks.” This points to the soft yet resilient nature of the rubber, which can form an airtight barrier when properly seated.
The thickness of 0.165 inches is adequate to prevent leaks without causing any difficulty when screwing the housing back together. The material, commonly BUNA-N or a similar nitrile rubber, withstands water exposure and typical variations in filter system pressures.
You should always clean the housing and old O-ring grooves before inserting a new ring. The pack of five means you won’t need to rush replacements, helping keep your system in top shape with a fresh, robust seal each time.

Real-World Performance
In everyday use, these O-rings have proven to provide a solid, leak-proof seal for Big Blue water filter housings. One homeowner shared their experience, citing how after replacing their old, cracked seals with these O-rings, their unit was leak-free through several filter changes and months of steady water flow.
The durability is noticeable; even after multiple cycles of removal and reinstallation, the rings retain flexibility without cracking. Applying a small amount of food-grade silicone lubricant before installation greatly improves the seal and extends the O-ring’s lifespan.
Also, these rings fit not only Pentek but a range of OEM housings, meaning if you’re managing different brands of water filter housings, the 151122 kit offers dependable compatibility. The pack of five ensures you’re set for multiple maintenance cycles or several systems.

Expert Advice to Maximize Results
When replacing the 151122 O-rings, always clean the groove inside the filter housing thoroughly. Dirt or residue can prevent a proper seal. Apply a thin layer of food-grade silicone lubricant to the O-ring before installation—it helps prevent pinching and extends the life of the rubber.
Avoid overtightening the filter housing after installing the O-ring to prevent damage. Hand-tight is usually sufficient to create a secure seal. Store unused O-rings in a cool, dry place away from direct sunlight to keep the rubber supple.
Check your O-rings regularly as part of your water filter maintenance routine. Early replacement before signs of wear prevents leaks and prolongs the lifespan of your filtration system.
