Flex Caulk US600CLR200 Clear Silicone Caulk Sealant

Product Description

The FLEX CAULK US600CLR200 is a 100% silicone caulk sealant in a clear finish, designed for sealing joints, seams, and penetrations in residential and commercial applications. The product ships in a self-contained applicator with an adjustable trigger-flow nozzle, eliminating the need for a separate caulking gun. Flow rate is controlled directly at the nozzle, and flow stops when the trigger is released, reducing drips and overrun. Licensed plumbers, HVAC technicians, and general contractors reach for this type of sealant when sealing pipe penetrations, duct connections, and interior or exterior joints that require a flexible, watertight bond.

The US600CLR200 is suited for use on a range of substrates including metal, glass, ceramic, and most plastics. The clear silicone formula cures to a flexible bead that accommodates movement without cracking, making it appropriate for expansion joints and areas subject to vibration or thermal cycling. Its self-contained dispenser format is useful in service environments where carrying a caulking gun is impractical.

Installation Notes

Silicone sealants are applied by plumbers, HVAC technicians, and general contractors. Before applying, clean and dry the substrate thoroughly — silicone does not adhere well to wet, oily, or dusty surfaces. When sealing around live mechanical systems such as pressurized lines or energized electrical enclosures, de-energize or depressurize the system before work begins. Allow the sealant to fully cure per product instructions before exposing the joint to moisture or pressure.
