Features and Benefits:

An innovative press system which is quick and simple to install providing a secure and permanent joint.

3-point press design– one press each side of the bead, and one press compressing the O-ring.

Lead-in edge design aids installation and helps protect the O-ring from damage or displacement.

Suitable for air-conditioning and refrigeration applications up to 48 bar.

Flame-free installation avoids the need for a fire permit and the risk of fire on site.

Mechanical joint, eliminates the need for nitrogen purge during the jointing process.
