Sight gauges are available in several models including bolted, caged, non-caged fluoropolymer (FEP), polysulfone and view port. The discussed quality parameters and desired features may impact a customer’s sight gauge selection.

Sight gauges are an integral part of high stress applications for the food and beverage industry. Manufacturers require liquid level gauges rated for various pressure settings that are unaffected by sunlight or ultraviolet rays.
Manufacturers construct quality gauges from contamination, odor and taste resistant materials. Full length sight gauge windows permit easy liquid level viewing. Two heavy gaskets lock the sight glass firmly in place. A knurled, vented cap facilitates easy cleaning.

Optional sight gauge features include vented assorted sizes, reservoir use and rotating shields. Valves may use a stuffing box configuration to seal the glass tube. Consider the type of glass tube and center-to-center length, as both specifications impact the pressure rating.

An established supplier offers a broad range of sight gauges to satisfy the most discerning customer. ...
... Sight gauges are available in a variety of styles including bolted, caged, non-caged FEP, polysulfone and view port.

Bolted sight gauge acrylic inserts are appropriate for use at 180°F. The Pyrex insert temperature rating relies upon the temperature rating of the gasket used in the application. End connections are available in custom alloys, 316L Stainless Steel Fittings or Tri-Clamp®. The bolted sight gauge comes standard with Buna-N seals. FKM fluoroelastomer silicone upgrades are available upon request. End configuration options include bevel seat, butt weld, I-line and Q-line.

Caged sight gauges perform in temperatures ranging from 14°F to 302°F. Non-caged FEP sight gauges are appropriate for use in temperatures ranging from -100°F to 400°F. Both products are reliable in high stress applications. Features include discoloration resistance, liquid level indicators, a non-stick surface, and shatterproof tubes. End connections for sight gauges are available in DF/ISS, DIN, RJTI, SMS and Tri-Clamp® varieties.

Polysulfone sight gauges perform in temperatures ranging from -20°F to 240°F. Molded end connections are available in Maxi Tri-Clamp® and Tri-Clamp®.

View port sight gauges use mechanically pre-stressed windows made of secure, strong sanitary sight glass. The glass elements offer optimal optics and strength, providing increased safety and service life. View ports are ideal for processing and inline visual flow indicator applications. View port efficiency is superior to plastic or tempered glass. Glass shattering or leakage does not occur, despite extreme temperatures or overpressure situations.

Leading suppliers furnish quality products that cater to a client’s specific requirements. Sight gauges are an integral part of a hose supplier’s product line. Types of hoses typically carried by reputable suppliers include convoluted polytetrafluoroethylene (PTFE), Food and Drug Administration (FDA) approved polyvinyl chloride (PVC,) FDA approved rubber, heater, metal, metal detection silicon and smoothbore fluoropolymer. Leading suppliers also offer hose accessories including adapters, anti-microbial products, hose fittings, o-ring gaskets sanitary clamps, sanitary gaskets and validation products.

Reputable suppliers commit to service and support. Such suppliers combine innovative technology with stringent quality specifications to ensure customer satisfaction. To learn more about sight gauges, hoses and hose accessories visit .
