LINK-LOCK FKM Sealing Gasket O-Ring Set 5pcs

Description

Product Overview

The LINK-LOCK FKM sealing gasket set is a compact collection of five O‑rings engineered for high‑stress automotive applications. Constructed from fluorocarbon rubber (FKM), the material delivers exceptional resistance to oil, fuel, coolant, and a wide temperature range from -40°C to 200°C. Each ring is precision‑molded to meet OEM specifications (part number 11517788984) and undergoes a secondary vulcanization process that enhances dimensional stability and longevity. The package dimensions are 3.94 x 3.94 x 0.39 inches, weighing only 1.41 ounces, making it easy to store and handle in any workshop.

Usage

These gaskets are intended for replacement of intake and exhaust manifold seals on a variety of vehicle models, particularly those identified by the M47 and M57 engine families. They excel in environments where high pressure, vibration, and exposure to aggressive chemicals are common, such as performance tuning, routine maintenance, and emergency repairs. Mechanics, service centers, and automotive enthusiasts will find the set convenient for quick swaps, reducing downtime and preventing costly leaks.

FAQ

What vehicles are compatible with this gasket set?

The set is designed for engines identified as M47 and M57, commonly found in several European and Asian models. Always verify the OEM part number 11517788984 against your vehicle’s service manual.

Can these gaskets handle high boost pressure?

Yes. The FKM compound is rated for high pressure environments and maintains its sealing integrity under turbocharged or supercharged conditions.

How does secondary vulcanization improve performance?

Secondary vulcanization further cross‑links the polymer chains, reducing compression set and preventing the O‑ring from flattening after repeated heating and cooling cycles.

Are these gaskets suitable for chemical processing equipment?

While primarily marketed for automotive use, the chemical resistance of FKM makes the rings appropriate for many industrial sealing applications, provided the temperature and pressure limits are respected.

What is the recommended installation torque?

Install the O‑rings with a uniform hand‑tightened pressure. Excessive torque can deform the ring, while insufficient pressure may lead to leaks. Follow the vehicle manufacturer’s torque specifications for related fasteners.
