Flexible Metal Hose


HyVac Products has a number of products in this category. The most prevalent is stainless steel hose grade 321. 321 SS is what is stock available for vacuum work and is available from 1/4 OD - 6" OD and can come un-terminated or terminated. We often need to know exactly what you are trying to accomplish connecting what to what to give you a good price based on termination and acceptability. Remember the larger the diameter the better the vacuum flow so we also need your desired diameters.

321 Stainless Steel is known as an austenitic grade with the following partial metallurgical composition 17-19% Cr, 2.5-5% Ni, .08% C, 2% Mn,

.75% Si, .045% P, .030% S. We believe that in general the 300 series stainless steels are generically referred to as non-magnetic but there may be some kind of field present that still is considered "generically" non-magnetic. If magnetism is an issue see our bronze offering.

Generally we are able to braze on location to standard vacuum fittings. Brazing or welding seams are then hydrostatically tested. We can also leak test but this cost extra due to time and expense involved in helium leak testing.

We have a number of standard length hose sections already terminated in 4/10/20/40 inch lengths available at very good value.  Termination is typically standard quick release vacuum fittings.

Please see the new section under Fittings we have many standard 
lengths of 304SS flexible bellows listed including KF16,25,40,50 sizes 
lengths 4,10,20 and 40 inch.
