Zight for Distillery

Why consider Zight for your gauge glass?

Because we manufacture here instead of overseas, you’re not eating the cost to have German glass freighted across the Atlantic and storage in the US. As a result, we’ve got the quality level gauges you expect… but for quite a bit less than you might imagine.

What kind of product availability and order turnaround can I expect from Zight?

Often times, your customers need their sight glass ASAP. We manufacture and stock all the most commonly used glasses and lengths so there’s no worry on your end whether the tubes you need are available. And again, you can rest assured that the turnaround out of our facility in Kansas is usually within the same day of the order.

SIGHT GLASS WINDOW

The sight glass windows weldable to tank allow a total vision of the interior of a process. Depending on the fluid temperature and pressure to work, a recommendation can be made on the best manufacturing material, type of glass and type of packaging.

Custom window?
Sight Windows for Industrial Applications can have a lot of specifications, because the product they will deal with is not the same. Make sure to talk to our Zight representative about your needs and we will be happy to provide you with detailed project and quote.

How can I be sure that I get a top-quality glass?
All Circular Tempered Boro Disc glasses which claim to be high quality need to be melted, machined, tempered, and tested according to the same international standard. If it is DIN7080, it is quality.

TEMPERED BOROSILICATE CIRCULAR SIGHT GLASS

Manufactured in 3.3 Borosilicate Glass, these sight glasses are used in several applications where a good chemical resistance and low thermal expansion coefficient are required. A bad chemical resistance may cause glass to react and release unwanted substances in the process, such as arsenic which is formed when a non-borosilicate glass reacts with water.

Custom size? No problem!
Special dimensions of glasses are available upon request, where the minimum diameter is 2/5”, and the maximum diameter is 13.78”. The thickness can be manufactured to a minimum of 1/8” and a maximum of 1 3/8”. Do not hesitate to contact us for recommendations as to which sight glass fits your application the best.

LEVEL GAUGE GLASS VALVES FOR TANKS - STAINLESS STEEL

The ZIGHT level gauge glasses made of STAINLESS STEEL allow a view of the level in a tank. The valves are forged in a single piece, which guarantees excellent resistance to pressure and the most adverse conditions. The equipment is designed to work in different tanks, the standard connection is 1/2 ”NPT or 3/4” NPT; the design pressure of the level valves is for 500 PSI. They can also be manufactured in 1” NPT and 1-1/2” NPT. Depending on the working pressure and working temperature to work, the type of level tube will be recommended (standard wall, high-pressure wall, or extra-reinforced wall. In the same way, appropriate gaskets can be recommended, these can be made of Viton, EPDM or Teflon. The equipment can have protective rods, these can be made of 304 stainless steel threaded at the ends; or in aluminum pressed in the upper part.

Custom tubes? No problem!
We manufacture our tubes using Borosilicate 3.3 Industrial Grade glass at lengths up to 145” down to ½”. We can also accommodate a variety of OD and wall thickness requests; from ¼” to 12” OD and from 1/16” to ⅜” thickness. We can make whatever tube you need for the project at hand. Click to browse the full catalog of products.

Better Safety Factor
While we offer the same pressure ratings, our glass has a larger safety factor due to the increased wall thickness giving you and your customers a safer, more reliable tube.

LEVEL GAUGE GLASS ESG ENVIRONMENTAL SEALED GAUGES

The Environmental Sealed Gauge (ESG) is a complete Gauge Glass protection system that helps to prevent costly spills due to a broken gauge. The ESG uses transparent poly and two, piece nozzles along with gauge glass to make up the assembly. The ESG is ordered in two different forms, the field kit and the custom assembly. The field kit standard comes in either a 48” or 72” VISUAL kit, meaning if a 48” kit were assembled straight out of the box the visual gauge would be 48” long and the overall length of the ESG would be 52.75”. Each ESG comes with instructions for how to cut and assemble your ESG based off of your Center to Center and Gauge Cock style. The Custom Assembly is fairly self-explanatory, we would need to know your Center to Center and gauge cock style to cut and assemble before shipping to our customers.

RED LINE AND TRANSPARENT GLASS TUBE

Manufactured in 3.3 Borosilicate Glass, these level gauge glass tubes are used in several applications where a good chemical resistance and low thermal expansion coefficient are required. Zight Glass Tubes are available in different wall thicknesses according to customer specifications, and both in Red Line and Transparent . The Red Line tube is treated with a special Paint (two White lines and one red line) which creates an optical effect that magnifies the level of the fluid, and allows a distant and quick inspection.

Custom tubes? No problem!
We manufacture our tubes using Borosilicate 3.3 Industrial Grade glass at lengths up to 145” down to ½”. We can also accommodate a variety of OD and wall thickness requests; from ¼” to 12” OD and from 1/16” to ⅜” thickness. We can make whatever tube you need for the project at hand.

BUBBLE TRAP

ZIGHT sight glasses with bubble traps allow the user to remove bubbles that are naturally formed in processes such as distillation, evaporation and various chemical reactions. The most common measurements in which they are manufactured are with 3 sanitary CLAMP connections, one at the top that works as a vent for gases; and two in the lower part, the central connection is the one that supplies the fluid to the system, and the lateral one is the drain of the same fluid. These types of sight glasses are commonly used in distilleries and in chemical processes where the mixture of fluids causes unwanted gases in the system.

360° Full-View
Made of ZIGHT GLASS Borosilicate 3.3. and fully tempered, the glasses are used for optical control in lubrication devices, as well as observation ports in 360° sight glasses.

TEMPERED BOROSILICATE CYLINDERS

A Tempered Cylinder, unlike many of the glasses in the market, is not only cut from an existing tube. In order to ensure a correct seal and facilitate assembly, all cuts are ground-square and polished. Additionally, all the sight glasses as well as the lubrication tubes are subjected to a tempering treatment which drastically improves their mechanical resistance characteristics, therefore avoiding chipping and being able to withstand higher working pressures and increasing the duration.

Custom size? No problem!
The Zight Cylinders can be manufactured in any size, both in the English metric system or the international one. However there are some sizes which are mostly used due to market standardization. The length for these standard sizes usually varies depending on the manufacturer.
