The OATEY COMPANY 25220 is an 8-ounce jar of yellow pipe thread compound designed to seal threaded pipe connections in gas and liquid distribution systems. Formulated as Formula 55 Thread Seal, it works on all metal fittings as well as plastic pipe materials including PVC, CPVC, ABS, and nylon. The compound is rated for gas service up to 3000 psi and liquid service up to 6,000 psi, making it suitable for a wide range of pressure applications. Its slow-drying formula never seizes on threads, preserving the ability to disassemble joints cleanly after service. Licensed plumbers and pipefitters rely on this compound for routine thread sealing on gas and water distribution systems.
This compound is intended for use on LP and natural gas lines as well as liquid-carrying lines in residential and light commercial plumbing systems. It bonds to all standard metal fittings and is safe for use on thermoplastic pipe materials where solvent-based sealants may cause degradation. Typical applications include threaded connections on gas appliance supply lines, water service piping, and general-purpose pipe assemblies requiring a durable, pressure-rated seal.
Suitable for use on LP gas lines, natural gas lines, and liquid-carrying pipe systems. Compatible with all metal fittings and plastic pipe materials including PVC, CPVC, ABS, and nylon threaded connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where required. Shut off gas or water supply and depressurize the line before applying compound and making up threaded joints. Apply compound evenly to male threads before assembly. Allow adequate cure time before repressurizing the system and testing for leaks.
