Silver King SKBS 16 oz Boiler Solder Trap

This 16 oz boiler solder trap is designed for steam and hot water boiler maintenance. It stops leaks by forming a water-insoluble seal in both old and new installations. The product has served this purpose for over 60 years and contains no petroleum. It is non-hazardous and compatible with anti-freeze solutions.

Replaces temporary leak fixes and repeated patching

The solder trap upgrades from short-term sealants that break down under heat and pressure. It creates a permanent water-insoluble bond that withstands boiler operating conditions. The jump is worth it when leaks persist in steam or hot water systems and a durable, non-petroleum seal is required. Do not use in boilers with submerged coils.

Fits standard boiler drain and trap connections

The unit installs directly into existing boiler drain components for leak repair. It frees up maintenance time by eliminating recurring leak checks and reapplications. The non-hazardous formula works safely with anti-freeze already in the system. Use SAFE Liquid Boiler Stop Leak for compatible liquid treatment needs.

Questions about this item

Does the 16 oz container fit a standard boiler drain opening?

The product is a 16 oz boiler solder compound applied directly into the system, not a mechanical trap that mounts to a drain opening.

How do I add the solder to a steam boiler, and what step is often missed?

Add the solder through the boiler's safety valve or petcock while the system is warm and circulating; the step often missed is ensuring the boiler has no submerged coils before treatment.

Will the seal hold up with antifreeze in the system, or must I reapply it seasonally?

The solder is compatible with antifreeze and forms a water-insoluble seal designed to last; it has stopped leaks in boilers and hot water systems for over 60 years without needing seasonal reapplication.
