L H Dottie Co RTV8W Rtv Silicone Sealant White 2.5 Oz

Product Description

The L H DOTTIE CO RTV8W is a white, single-component RTV (room-temperature-vulcanizing) silicone sealant packaged in a 2.5-ounce tube. RTV silicone cures on exposure to atmospheric moisture and forms a flexible, durable seal resistant to temperature extremes, vibration, and moisture. It is widely used by electricians, HVAC technicians, and plumbers to seal conduit penetrations, junction box entries, pipe penetrations through walls or floors, and equipment housings where a clean, finished appearance is required. The white color makes it suitable for visible applications where aesthetics matter alongside performance.

This sealant is appropriate for residential and light commercial trade applications. Electricians use it to seal conduit and cable entries to prevent air, moisture, and pest infiltration. HVAC technicians apply it around line-set penetrations, equipment cabinet seams, and sheet metal joints. Plumbers use it for sealing non-pressurized pipe penetrations and fixture surrounds. The compact 2.5-ounce size is suited for service calls and small jobs where a full-size cartridge would be excessive.

Key Features

• White color blends with painted surfaces and finished wall penetrations
• Single-component formula cures at room temperature without mixing
• Flexible cured seal resists vibration, moisture, and temperature cycling
• Compact 2.5-ounce tube for portability on service calls
• Suitable for sealing conduit, pipe, and equipment penetrations

Compatibility

Designed as a general-purpose RTV silicone sealant for use in electrical, HVAC, and plumbing penetration sealing applications on common substrates including metal, glass, and most rigid plastics.

Installation Notes

Application is typically performed by licensed electricians, HVAC technicians, or plumbers as part of a penetration sealing or weatherproofing workflow. Surfaces should be clean, dry, and free of oil or loose material before application. Allow full cure time before exposing the sealant to moisture or mechanical stress. Consult local building codes, NEC requirements, or applicable mechanical codes for firestopping requirements at rated assemblies, as standard RTV silicone is not a listed firestop product.
