Description

The Pentair 072184 stainless steel flat washer is built for durability in demanding pool and spa gear. Made of 18-8 stainless steel, it resists rust and stands up to heat, moisture, and repeated stress. With a 3/8" inside diameter and 13/16" outside diameter, this washer is engineered to properly distribute pressure across seal plates and housings in Pentair MiniMax heaters and many pump systems—IntelliFlo, WhisperFlo, SuperFlo, EQ-Series, and more. Its precision sheet thickness maintains structural integrity without introducing unwanted gaps.

Pro Tip

Inspect mating surfaces (seal plate and pump housing) for pitting or corrosion when replacing washers—an imperfect surface can reduce sealing effectiveness. Also consider replacing bolts or gaskets in the same assembly to ensure a full, reliable seal.

Installation Tips

Turn off power and relieve system pressure before opening heater or pump housing. Ensure replacement washer is clean and flat; avoid overtightening bolts—stainless washers can deform under excess torque. Verify dimensions match original part before installation.
