3K & 3K2 Rubber Bellows

Enquire About This Product

Share:

Description:

In addition to their flanged compensator range, Vibracoustics Ltd offer the 3K and 3K2 rubber expansion joints, especially to provide small, low weight expansion joints that are both very flexible and simple to install and provide the ideal service connection where avoidance of noise transmission is a key factor.

The 3K ranges accommodate misalignment, axial and lateral pipe work movements and dramatically reduce the transmission of noise, vibration and shock.

Specification:

The expansion joints are manufactured in black Nitrile rubber, reinforced with synthetic fabric to achieve a high mechanical strength. They are suitable for use with cooling water, fuel and lubrication oil pipe work systems up to 90 deg.C. The burst pressure safety factor is 5 times the working pressure of 4 bar. The minimum working pressure (absolute) is 70 kPa but can be lowered by fitting a vacuum support ring.

Alternative rubber specifications and sizes are also available for other applications on
request.
