Pentair 1.5" Triton® II Threaded Cap

The Pentair 1.5" Triton® II Threaded Cap (part number 154512) is a specialized replacement closure designed for the threaded ports of Pentair Triton® II series side-mount pool and spa sand filters. Molded from rigid, high-impact, and chemical-resistant PVC, this heavy-duty cap functions as a secure structural seal for the filter's winterizing drain opening or auxiliary port, ensuring a tight, leak-proof barrier capable of safely containing the intense internal hydraulic pressure generated during standard filtration cycles. This threaded cap is engineered with raised external ridges or a hex-shaped pattern to provide service technicians with adequate manual leverage during installation or winterization maintenance. While robust enough to withstand continuous outdoor weathering and harsh chemical exposure, this compact plastic hardware component is highly manageable and lightweight, carrying an actual product and shipping weight of approximately 0.14 pounds (about 2.2 ounces).
