KF Flexible Couplings St. Steel

These Flexible Coulings are made of Thin Wall Hydroformed Bellows. These Flexible Couplings have more convolutions compared to standard Bellows resulting in greater flexibility and stroke and lower spring rate. These Flexible Couplings are used for alignment or vibration isolation rather than as roughing lines. Maximum compression for Flexible Couplings is typically 20% of the convolution (flexible) length. Extension is typically 10%. Couplings are available in 321 or 316L Stainless Steel in various lengths.
