Midland Industries Caulks & Sealants

Overview

The MIDLAND INDUSTRIES 400132 is an FKM O-ring engineered for hydraulic sealing applications requiring chemical resistance and high-temperature performance. With a 2.5-inch inner diameter and a cross-section thickness of 0.1 inches, this O-ring is sized for a 2-1/2-12 thread size SAE Boss 90-degree connection. FKM (fluoroelastomer) construction provides robust resistance to oils, fuels, and hydraulic fluids, making it a reliable choice for demanding hydraulic system service. It is rated to withstand temperatures up to 375 degrees F, suitable for high-heat environments found in industrial and mobile hydraulic equipment. This O-ring is used in hydraulic plumbing applications where an SAE Boss 90-degree fitting connection requires a static face seal. It is commonly installed during hydraulic line assembly or repair on mobile equipment, industrial machinery, and power units. The imperial measurement system sizing makes it straightforward to match against existing hardware for maintenance and replacement work performed by hydraulic technicians and fluid power mechanics.
