Industrial RTV Silicone Gasket Maker – No Caulking Gun Required

Professional-Grade Black Silicone for Precision Gasket Application and Industrial Equipment Maintenance

Forget traditional RTV silicone cartridges that require a separate caulking gun. ZenaGasket Black delivers industrial-strength, low-volatility RTV silicone in a convenient, self-dispensing aerosol can.

Simply remove a can from the case and apply a controlled bead of silicone directly to the mating surface. No cartridge loading or separate dispensing gun is required.

Designed for industrial maintenance technicians, mechanics, and equipment service professionals, ZenaGasket Black forms flexible, in-place silicone gaskets for machinery, gearboxes, compressors, motors, pumps, and other equipment.

Common applications include:

  • Industrial Gearboxes – Forming flexible gaskets on gearbox covers and mating surfaces.

  • Electric Motors – Sealing suitable motor housings and equipment covers.

  • Air Compressors – Creating in-place gaskets on compatible compressor components.

  • Machine Covers – Sealing equipment access covers and mechanical assemblies.

  • Oil & Transmission Pans – Replacing suitable conventional gaskets.

  • Oil & Water Pumps – Sealing pump housings and mating surfaces.

  • Valve & Timing Chain Covers – Forming flexible silicone gaskets on engine components.

  • Electrical Control Boxes – Sealing compatible enclosures and covers.

ZenaGasket Black adheres to properly prepared metal, glass, ceramic, vulcanized rubber, many wood surfaces, and compatible painted or plastic materials.

How to Apply ZenaGasket Black

1. Prepare the Surface

Clean and dry all mating surfaces. Remove oil, tar, dirt, dust, and other contaminants that could interfere with adhesion.

2. Apply a Precise Silicone Bead

Hold the can at approximately a 45-degree angle and dispense a continuous bead measuring 1/16" to 1/8" onto the mating surface.

Encircle all bolt holes to help create a continuous gasket seal.

3. Position the Components

For adhesion to both mating surfaces, assemble the components immediately.

For adhesion to only one surface, allow approximately 10–15 minutes for the silicone bead to develop a skin before assembly.

4. Assemble Carefully

Install and tighten the components according to the equipment manufacturer's requirements. Avoid overtightening bolts and squeezing the silicone gasket out of the joint.

5. Allow Proper Curing

Curing begins immediately after application. The manufacturer specifies approximately 24 hours for full cure, with optimum strength reached after seven days.

A More Convenient Way to Make Industrial Gaskets

Traditional RTV silicone cartridges require maintenance personnel to carry a separate caulking gun. ZenaGasket Black provides the convenience of a self-contained dispensing system, allowing technicians to apply silicone directly from the can.

Whether servicing industrial gearboxes, replacing machine-cover gaskets, maintaining compressors, or repairing mechanical equipment, ZenaGasket Black combines precise application with the durability, adhesion, and permanent flexibility of professional-grade RTV silicone.
