Tri Clamp Sight Glass(Union)

If your pot/boiler has tri clamp ferrules on the dome, this tri clamp sight glass is the ideal solution for adding a viewing glass to inspect the contents. It can also function as a blocking plate for the ferrule while still allowing for a see-through port.

I’m a welder and fabricator by trade and Was pleasantly surprised at the quality of the products I ordered! Reasonably quick on the delivery in terms of where it’s coming from ! I will be ordering more as soon as this review is done!

Items in stock typically can be shipped within 7 work days by Fedex/UPS/DHL/Yanwen(7-9 work days to the US, Canada, Australia, NZ, UK and Europe), for returns please email us directly.

We provide one year warranty for all of the items sold in this site excluding gaskets&seals. Warranty period starts on the date of delivery and we will also cover postage for replacements.

One of the reasons that the shipping costs on Pipe Fittings are calculated&charged separately is that the shipping rate(per KG) would drop when shipment gets heavier. We want to pass this benefit direcrly on to our customers. For example today(May 15, 2023) UPS Expedited's price for a 1kg shipment from China to the US is USD 23 and for a 11kgs shipment it's USD 91 by Fedex IP(6-9 work days), which would be USD 91/11=8.2 USD per kg, it's a big difference compared to the rate of 1kgs shipment and the gap would be even bigger when there's multiple items in your cart.

It's also a fact that the items such as gaskets, ferrules, adaptors, reducers and clamps are not heavy and in many cases they are less than 0.5kgs, it saves money if we do combined shipping and not include shipping costs in the price of each of items.
