Urethane Drive Coupling Insert, 500 Series, 90A

Magnaloy Coupling’s full range of flexible inserts permit custom design performance for a wide range of applications. All insert materials offer complete electrical insulation, as Magnaloy’s design eliminates all metal-to-metal contact.

Neoprene – Black material – Standard material with Magnaloy Coupling. Good general purpose material offering good resiliency and load capabilities. Temp range -300F to +2500F (-340C to -1210C). Optional 80A durometer (painted Gold) and 90A durometer (painted Silver) are available for slight increased load capability and less resiliency.

Nitrile – Painted Blue. Excellent material with petroleum products. Excellent compression set and abrasion resistance characteristics. Temp range -600F to +2500F (-510C to +1210C).

Urethane – Yellow material. Excellent mechanical and physical properties. Offers good medium duty durability and resiliency. Urethane tends to soften at higher temperatures and humid conditions. Temp range -300F to +1500F (-340C to +660C).

Viton – Red material. Excellent fluid compatibility and high temperature characteristics. Good compression set and resiliency. Temp range -200F to +3500F (-290C to +1770C).

Hytrel – Blue material. Superior physical and mechanical properties and excellent fluid compatibility and high temperature characteristics. Hardness (50D) approaches that of plastic and offers little resiliency. Excellent performance under heavy duty conditions. Temp range -650F to +3000F (-540C to +1490C).
