SANEI's "PM50 Insulation Cap" is a repair part for the insulation pipes used in their mixing faucets and other products. Made of ABS resin, it prevents burns from hot water and enhances insulation. Replacement is relatively easy; you can remove the flow straightener body, pull out the retaining pin, and replace the cap. You can check the compatible faucet model numbers on the product packaging or the manufacturer's official website. Recommended for those considering replacement or maintenance, and for those who own compatible models. #Click here for a list of Meerkat-related products #Click here for a bulk sale of Meerkat products
