Is Pipe & Flange Sealer AN30-572, Pen Applicator safe for use on potable water systems?

Yes. Pipe & Flange Sealer AN30-572, Pen Applicator Format is safe for use on potable (drinking) water systems. It is KTW-approved for drinking water installations and DVGW-certified for gas and hot water systems, meeting high industry safety and compliance standards. Its formulation with PTFE, resistance and durability across -60°C to +150°C, and suitability for threads up to M80 make it appropriate for potable water applications while allowing disassembly with standard tools for maintenance.

Can Pipe & Flange Sealer AN30-572, Pen Applicator be used on threaded connections exposed to temperatures near its upper limit (+150°C)?

Yes — Pipe & Flange Sealer AN30-572, Pen Applicator Format can be used on threaded connections exposed to temperatures near its upper limit of +150°C, but with the following considerations: - The product’s specified operating range is -60°C to +150°C, so using it at or slightly below +150°C remains within its rated performance envelope and is intended by the manufacturer. - At temperatures close to the upper limit, chemical and mechanical properties (cure rate, viscosity, long-term strength, and resistance to thermal cycling) can be more stressed than at lower temperatures. Expect normal sealing performance, but allow for the possibility of slightly reduced long-term durability compared with moderate temperatures. - Because the sealant is medium strength and designed to allow disassembly with standard tools, threaded joints should still be serviceable after exposure near +150°C, provided assemblies are not subjected to excessive torque or prolonged thermal cycling beyond the rating. - The product’s DVGW and KTW certifications and PTFE-enhanced formulation support its use in demanding gas, hot water, and drinking water applications at rated temperatures. Recommendation: For continuous or frequent operation at +150°C or where maximum long-term reliability is critical, consider validating in your specific application (e.g., test a sample joint under actual service conditions) or consult the manufacturer’s technical datasheet/technical service for confirmation.
