More durable than plastic caps, these provide the most protection from abrasion and impact.

Also known as freeze plugs, these are commonly used to permanently seal the shallow holes left in a component during the casting process.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Use these corrosion-resistant fittings in a low-pressure pipe line.

Use these heavy duty forged flanges for high-pressure applications.

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

Protect harsh environment M12 connectors when not in use.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these vents allow air to flow through enclosures to maintain consistent pressure and reduce moisture buildup as temperatures change. They also stand up to washdowns.
