SMS threaded sight glass with OD 102 mm stainless steel welded observation mirror. Built in SS304 for durability and corrosion resistance, this component provides a secure, sanitary viewing point for process vessels and piping with SMS threaded connections. Key benefits Instant visual inspection: Lets operators view liquid level, color, flow, or process conditions without opening the system, reducing contamination risk and downtime. Robust, lowmaintenance construction: Welded stainless steel assembly resists mechanical wear and corrosion for long service life in industrial environments. Simple integration: Designed for SMS threaded installations — fits systems and fittings that use SMS thread standards and a 102 mm outer diameter. Product highlights Connection type: SMS threaded (compatible with SMS threaded fittings and process lines) Outer diameter (OD): 102 mm Material: SS304 stainless steel (body and welded mirror assembly) Construction: Welded observation mirror for a rigid, sealed viewing point Primary function: Provides a clear observation port for tanks, pipes, and vessels Why customers choose this product Visibility without exposure: Observe internal processes without interrupting pressure or sanitary conditions. Durable sanitary material: SS304 is widely used for process equipment because it balances corrosion resistance, strength, and cleanability. Reliable joint: Welded mirror assembly reduces potential leak paths compared with removable or clamped assemblies. Typical applications Food and beverage production: Monitor product flow, clarity, and level in sanitary lines, tanks, and heat exchangers that use SMS threaded connections. Brewing and fermentation: Visual checks of wort, fermentation activity, and transfers without opening vessels. Pharmaceutical and chemical processes: Observation port for reactors, mixing vessels, and piping where contamination control and visual monitoring are required. Installation and maintenance notes Intended for use with SMS threaded systems; verify mating thread compatibility before installation. Install using the appropriate SMS threaded fittings or adapters and follow standard welding and assembly practices for your process line. Clean with nonabrasive, compatible cleaners suitable for SS304. Inspect periodically for signs of damage or wear. Ordering considerations Confirm system uses SMS threaded fittings and that a 102 mm OD sight glass matches your mating components. Material specified as SS304. If a different alloy or surface finish is required, select an alternate product designed for that specification. This SMS threaded sight glass OD102mm in SS304 provides a simple, durable solution for inline observation where a welded stainless steel mirror and SMS compatibility are required.
