Viewport Installation Kits

 

 

 

Viewport Installation Metric Bolt kits

It is always exciting getting your hands on one of our high-precision vacuum viewports. However, the excitement can be cut short when you realise you haven’t got the correct bolt set to install it.

 If this is you, there’s no need to blow a gasket!

As part of a range of viewport accessories, we now offer metric bolt viewport installation kits for Conflat® flanges.   The kits are designed to be used with either tapped or through-hole flanges.  Through-hole kits will include hex-head bolts, tapped flange kits will include cap head bolts.

As standard, the through-hole kit will come with stainless steel bolts, silver‑plated stainless-steel nuts, stainless-steel washers and an annealed copper gasket.
The tapped version will come with silver-plated stainless steel bolts, stainless-steel washers and an annealed copper gasket.

We recommend silver-plated nuts or bolts for bake-out applications. High temperatures can cause the nut/bolt interface to ‘cold weld’ over a period of time.  It is then difficult to undo the joint, tapped threads are easily damaged (and they are not always easy to repair).

Annealed copper gaskets require a much lower sealing force to make a leak‑tight seal. We always recommend these for use with our wide range of viewports.

If you’re not quite sure which accessories best fit with your brand-new viewport, we’ll be happy to advise.

(*) non-metric bolt kits are also available, details on request.
