All fittings are fabricated from type 304 stainless steel drawn and welded vacuum tubing. Flanges do not need to be rotatable since they are completely symmetric. If desired, Rotatable Bolt Ring Assemblies can be retrofitted to existing Claw-Clamp style flanges to add bolt holes to ISO LF fittings.
Reducers are used for a change in size of flanges within a single method of sealing, such as elastomer sealing of ISO KF and LF flanges.
Adapters are used to change from one method of sealing to another, such as elastomer seal ISO to metal seal CF.
