Product Description

The DOW CORNING 3140717 is an RTV silicone joint sealant in a 3 oz tube, part of the 732 series. It cures at room temperature to form a flexible, durable seal rated for continuous service from -76 degrees F to 356 degrees F. With a tack-free dry time of 20 minutes and a full cure time of 24 hours, it suits time-sensitive service work. Certified to 21 CFR 177.2600 and MIL-A-46106, this sealant is food safe and meets military spec requirements. It is used for gasketing, sealing, and bonding applications across HVAC, plumbing, and food-service equipment maintenance.

This sealant is suited for both residential and commercial applications where a flexible, temperature-resistant seal is required. It adheres to glass, metal, and plastic substrates, making it a versatile choice for sealing joints, forming gaskets in place, and sealing around fittings or housings. Technicians across HVAC, plumbing, and food-equipment service trades reach for this product when a fast-tacking, food-safe silicone sealant is needed in a convenient small-tube format.

Installation Notes

Clean and dry all mating surfaces before applying sealant to ensure proper adhesion. Apply a continuous bead and allow a minimum of 20 minutes tack-free time before handling; allow 24 hours for full cure before exposing the joint to fluids or pressure. Follow applicable codes and manufacturer guidelines for gasketing materials in pressurized or food-contact systems. Do not apply over wet, oily, or previously sealed surfaces without removing all residual sealant first.
