KF Sight Glass for MetaClamp(R), Borosilicate Fused to Hastelloy C-22 Housing

Sanitary KF sight glass for high vacuum and hygienic applications. Fits Swagelok(R) TS Fitting, Kwic-Clamp Flange geometry. Simple to install with no risk of breakage, this is a single-piece part ideal for use on food processing equipment (A3-Standard). Reliable against total failure - possibility of sudden unexpected rupture is totally excluded. This sight glass has a trade name MetaClamp(R) designed to be sealed to the process vessel with an elastomer gasket using a Tri Sanitary clamp. Standard KF clamps will also work but with less precision in clamping and without compliance for hygienic applications. This KF sight glass is manufactured to high tolerances and comes standard with surface finish 10 Ra microinches, with optional electropolish for improved cleanliness. Borosilicate glass DIN 7080 is fused to metal conforming to DIN 7079. Housing is made from Hastelloy C-22 (UNS N06022), with material certificate traceable to the metal manufacturer. Manufactured and tested in conformance with A.D. Standard Series H.P. & A.D. standard WO/TRD 100. The sight glass has an uninterrupted surface from glass to metal, with no crevices trapping bacteria. No epoxies, no internal seals, just pure borosilicate glass-to-metal fusion. Supplied with Certificate of Conformity to EN 10204-3.1B or 3.1A.
