FASTENER SEAL, STEEL PLATED,

APG stocks the AFS600-0101-3/8, a black Buna-N (Nitrile) Thread Seal supplied with an inside diameter of 0.375 in (9.53 mm). A thread seal combines mechanical fastening and fluid sealing in a single component. The catalog record notes: Nitrile 70 -3/8.

It resists propane and butane, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or ketones.

You will find this material specified across general industrial maintenance, construction equipment, and fluid power.

This item is sold individually under part number AFS600-0101-3/8. As always, verify media compatibility and operating conditions against the requirements of your specific application.
