Dap 754 Rtv Silicone Gasket Maker 2.8 Fl Oz Black

Product Description

The DAP 754 is a black RTV silicone gasket maker formulated for high oil-resistance applications in automotive and industrial service work. It cures at room temperature to form a flexible, formed-in-place gasket that eliminates the need for precut gasket stock. Rated for continuous service from -40 degrees F to 350 degrees F, this product meets ASTM C920 standards and is compatible with ceramic, fiberglass, glass, metal, plastics, porcelain, and rubber substrates. The 2.8 fl oz tube format delivers precise bead placement with minimal waste. Working time is 10 minutes, with full cure achieved in 24 hours.

This gasket maker is suited for sealing transmission pans, valve covers, oil pans, and similar automotive components where petroleum-fluid resistance is critical. It also sees use in light industrial maintenance involving pumps, gearboxes, and flanged joints where a molded-in-place seal is preferred over sheet gasket material. Technicians working in automotive shops, fleet maintenance facilities, and general industrial maintenance will find the tube format practical for both scheduled service and field repair tasks.

Key Features

• Higher oil resistance than standard RTV gasket makers, suitable for transmission and engine sealing applications
• Cures in place at room temperature, eliminating the need for precut gaskets
• Wide service temperature range: -40 degrees F to 350 degrees F
• 10-minute working time allows for part alignment before the bead sets
• Meets ASTM C920 sealant standard
• Bonds to ceramic, fiberglass, glass, metal, plastics, porcelain, and rubber

Compatibility

Designed for use on ceramic, fiberglass, glass, metal, plastics, porcelain, and rubber surfaces. Typical applications include transmission pans, valve covers, and other gasketed automotive or industrial joints requiring oil and water resistance.

Installation Notes

Clean and degrease all mating surfaces before applying the gasket maker to ensure proper adhesion. Apply a continuous bead of appropriate diameter to one mating surface, then assemble the joint within the 10-minute working time. Allow a full 24-hour cure before introducing fluids or returning the assembly to service. This product is typically applied by automotive technicians and industrial maintenance mechanics; follow applicable shop safety procedures when working with petroleum-based fluids during disassembly.
