Compatibility / Fitment Notes
BOSS 315 PLB103C is a general sealing product rather than a model-specific pool replacement part. Current pool-industry sellers list the silicone for pool equipment, PVC fittings, and related repair applications, but that does not mean it should automatically be used on every pool component or material.
Confirm that silicone sealant is appropriate for the specific surface, fitting, gasket, equipment component, or repair before application. Follow the equipment and sealant manufacturer’s instructions, particularly when sealing components exposed to pressure, water, chemicals, or heat.
Installation / Use Notes
Prepare and use BOSS 315 according to the manufacturer’s instructions. Apply only to clean, properly prepared surfaces that are compatible with the sealant, and allow the silicone to cure as directed before putting the repaired component back into service.
Do not substitute general silicone sealant for a manufacturer-specified adhesive, gasket compound, thread sealant, or specialized underwater repair material unless the applicable instructions permit it.
Buy with Confidence
