Pacer RTV Silicone LV Grade Clear Instant Gasket Sealant

Description

clear RTV silicone is a one-component instant gasket material for sealing, bonding, and flexible repairs where a visible joint needs a cleaner look than black or red gasketing compounds. Chemical Concepts lists oil, antifreeze, grease, and transmission-fluid resistance, while the Pacer product data sheet adds acetoxy silicone chemistry, 10 to 20 minute tack-free time, and full cure through 3.18 mm in 24 hours.

Clear RTV Silicone Benefits

• Clear cured appearance works well on glass, trim, and visible sealing points.
• Flexible cured gasket helps absorb movement instead of turning brittle.
• Continuous service range from minus 75 F to 400 F fits many engine-bay and maintenance tasks.
• Intermittent resistance to 500 F covers short heat spikes common in repair work.
• One-part format keeps field and bench use simple with no mixing step.

This material fits oil pans, water pumps, valve covers, thermostat housings, lights, hose connections, and electrical wire sealing. The product data sheet also calls out windshield glass, windows, leather, vinyl, polished wood, and plumbing-leak repair, which makes it a broad-use sealant for maintenance departments that want one clear silicone on the shelf for many small jobs.

Clear RTV Silicone Applications

• Replacing cut gaskets on covers and housings.
• Sealing glass, windows, and windshields.
• Insulating electrical wires and fixtures.
• Repairing hoses and light plumbing leaks.
• Flexible sealing on metal, rubber, vinyl, and leather.

Surface prep matters on any gasket replacement. Remove old gasketing material, clean oil and grease from the parts, and allow the joint to skin for about 15 minutes before assembling when the job calls for that sequence. The PDS lists 5000 psi pressure resistance, 325 psi tensile strength, 600 percent elongation, and Shore A hardness of 27 after 24 hours at 50 percent relative humidity.
