Hammer Union FIG100 – High Pressure Pipe Union

The Hammer Union FIG100 is a durable and versatile high-pressure pipe coupling engineered for marine and industrial applications. This figure 100 union operates at a working pressure of 3000 PSI (size dependent), providing a secure, leak-tight connection for hoses and pipes used in shipboard systems, offshore platforms, and general industrial infrastructure.

Manufactured from high-strength carbon steel, the FIG100 hammer union offers excellent resistance to corrosion, wear, and impact. The hammer nut design allows rapid make-up and break-out without the need for special tools—simply align the ends and strike the nut ears with a hammer. This makes it ideal for ballast lines, fuel oil systems, water transfer, and chemical lines where reliable, quick connections are essential.
