Loctite LOC59330 Silicone Sealant Rtv Black 80 Ml

Product Description

The LOCTITE LOC59330 is a black RTV (room-temperature vulcanizing) silicone sealant designed for forming flexible, durable gaskets and seals in demanding service environments. Sold in an 80 ml cartridge, it cures at room temperature to a resilient silicone rubber that resists vibration, moisture, and thermal cycling. The black color makes it a practical choice for applications where a neutral or color-matched seal is needed. Licensed plumbers, HVAC technicians, and general mechanical tradespeople reach for RTV silicone when assembling or servicing equipment that sees repeated heat and movement.

This sealant is suited for residential and light commercial applications including HVAC equipment housings, engine and mechanical covers, plumbing fixture joints, and electrical enclosure seals where a flexible, waterproof bead is required. It performs well on metal, glass, ceramic, and many rigid plastic substrates. The 80 ml tube format is appropriate for single-job use or small recurring service calls.

Key Features

• Black RTV silicone formulation cures to flexible rubber at room temperature without heat or special tools
• 80 ml cartridge size suits single-job and service-call applications
• Resistant to moisture, vibration, and thermal movement after cure
• Adheres to metal, glass, ceramic, and rigid plastic substrates
• Black color suitable for applications requiring a non-visible or color-matched seal

Compatibility

Designed as a general-purpose RTV silicone sealant for use on metal, glass, ceramic, and rigid plastic surfaces in HVAC, mechanical, plumbing, and electrical service applications.

Installation Notes

Surface preparation is critical — clean and degrease all mating surfaces before applying the sealant. Apply a continuous bead and allow full cure time before returning the assembly to service; cure rate varies with temperature and humidity. Work in a well-ventilated area, as uncured silicone sealant releases acetic acid vapors. Follow applicable codes and equipment manufacturer service procedures for the system being serviced.
