Masters

Masters, a brand from Oatey, began in 1947 with a single pipe thread sealant and has evolved into one of the most used and recognizable consumable brands in the Canadian plumbing and heating trades. While still primarily a pipe thread sealant brand, the Masters lineup now includes tools and accessories for sweat soldering, pipe threading, PEX joining, repair and maintenance, and waterproofing and sealing around tubs, showers, flues, vents, and stacks. Masters products are thoroughly tested by professionals to ensure a high-quality, first-time installation experience, and the brand provides resources such as SDS, product literature, BIM/Revit CSI specs, and case studies through Oatey.
