Know your boiler better when you use this tubular sight glass

Keystone Steam Supplies can provide all the tubular sight glass you need for your steam systems.

Tubular sight glass, also known as tubular gauge glass, is used on the outside of boilers and tanks to provide a simple, efficient way to check liquid levels. The sight glass is fitted between an upper and lower gauge glass valve that is mounted on the structure.

A variety of options for tubular sight glass are available from Keystone Steam Supplies. The different styles include high pressure and heavy wall, which come in either clear or red-line sight glass designs. 

Heavy wall: Heavy wall sight glass is designed for systems with higher pressures. This glass will stand up to the most heavy-duty applications, and will reduce your requirements for maintenance and replacement. It is available in outside diameters of 3/4 and 5/8 inches.

High pressure glass: This option is ideal for applications where the pressures and glass lengths require some extra strength, but do not quite call for the extreme durability of heavy wall glass. Keystone Steam Supplies offers high pressure glass with outside diameters of 1/2, 5/8 and 3/4 inches.

Clear vs. red-line sight glass: Keystone Steam Supplies can offer either clear or red-line tubular gauge glass. Red-line glass comes with a red background stripe that makes it easier to gauge the liquid levels inside your tanks, boilers or reservoirs. Clear sight glass should be used when you have a close-up view of the glass, or when you do not require a way to quickly check liquid levels.

In addition to its offering of tubular sight glass, Keystone Steam Supplies provides a wide variety of equipment for steam and hydronic systems. For example, to keep your sight glass protected from damage and your workers safe from injury, the company can supply the Gauge Glass Guardian — a durable polycarbonate safety guard.

These are just some of the offerings available from Keystone Steam Supplies. Imagine getting all your steam and hydronic heating supplies from the same place, guaranteed. Keystone Steam Supplies has what you need and will take care of the leg work, ensuring you get your products on time.
