Category: KF Bellows

Flexible bellows
Flexible stainless steel bellows are heat treated for maximum flexibillity and they are available in different lengths. Our flexible bellows have more convolutions than comparable products, resulting in greater flexibility and lower spring rates.

Flexible couplings
Maximum compression for flexible couplings is typically 20% of the convolution (flexible) length. Extension is typically 10%.

PVC hoses
PVC hoses can be used as a low cost rough vacuum line due to their higher outgassing rate. Although it can be bent relatively easily, it cannot be compressed or extended.
