Quick Product Summary

The BOSS 315 Clear Silicone Sealant PLB103C is a 3 oz tube of one-part silicone sealant designed for sealing and repair work. The clear formula cures to flexible silicone rubber and is listed as mildew resistant after curing, making it useful for many plumbing and pool-service applications where a compatible silicone sealant is required. Pool-industry listings specifically identify PLB103C for uses such as pool equipment and PVC-related sealing work.

Best For

  • Pool and spa equipment service
  • Plumbing repair and sealing
  • Small sealing jobs where a 3 oz tube is convenient
  • Pool service technicians carrying repair supplies
  • Applications requiring a clear silicone finish
  • Replacing or resealing components where the equipment manufacturer specifies a compatible silicone sealant

Why This Matters

  • Clear appearance helps keep finished repairs less noticeable
  • Flexible cured silicone accommodates applications where a rigid sealant may not be appropriate
  • Small tube size is practical for service calls and individual repairs
  • One-part design eliminates mixing before application
  • Resealable tube format helps make the product practical for maintenance work
  • Part number PLB103C simplifies product identification

The product is sold as a clear 3 oz tube with a reusable/resealable nozzle, and current listings describe it as one-part and flexible after curing.

Common Signs You Need This / Use This When

  • A pool or plumbing repair calls for compatible silicone sealant
  • Existing silicone has deteriorated and manufacturer guidance calls for resealing
  • You need a clear rather than white sealant
  • You are performing a small repair where a full-size cartridge would be unnecessary
  • You specifically need BOSS 315 / PLB103C
  • You need flexible silicone rather than a rigid sealing material

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

BOSS 315 PLB103C is clearly identified by product number, size, finish, and sealant type so pool owners and service professionals can verify the product before use.
