## Overview

LOCTITE SI 587 RTV Gasket Maker is a high-performance, metallic blue silicone sealant designed for automotive applications. It offers exceptional adhesion to all metals, resists cracking and shrinking, and cures quickly to form durable, oil-resistant gaskets that flex with engine movement. Ideal for valve covers, oil pans, and intake manifolds, it supports operating temperatures from -75°F to 625°F and is sensor-safe for modern engines.

## Description

"Failproof Flange Sealant LOCTITE® SI 587 RTV Blue Silicone Gasket Maker is used for gasketing and sealing applications for both plant maintenance and small, medium, and large-sized OEM. As a formed-in-place gasket/sealant, LOCTITE® SI 587™ has been designed to give outstanding performance in typical automotive gasketing applications including valve covers, rocker covers, oil pans, water pumps, end seals, intake manifolds, and rear axle housings. Excellent adhesive for bonding and repairing fabricated silicone gaskets. This product is typically used in applications with an operating range of -75° to 625°F (-54 °C to 260 °C.) Sensor-Safe Gasketing LOCTITE® SI 587 is formulated for oxygen sensor equipped engines. The product retains effective properties in contact with automotive fluids, such as motor oil, transmission fluids, alcohol and antifreeze solutions. It is typically used for valve covers, oil pans, intake manifold end seals, timing covers and transmission pans. NOTE: LOCTITE® SI 596 is not recommended for gasketing carburetors or fuel control devices where it will be in constant contact with hydrocarbon fuels. Material will develop excessive swell and loss of mechanical properties.

Review: Worthless, did not work. - Tube has no propellant, nothing came out of it when I tried to use it. Useless and can not be returned according to desertcart. Don’t buy! 0 stars if that was a choice.
