Combined Inline Flow Observation and Manual Sampling Port

This Tri-Clamp tubular sight glass integrates a manual rotary-knob sampling valve with a hose-barb/nozzle outlet directly into one of its stainless steel end flanges, while four exterior stainless steel tie bolts secure the replaceable tempered glass cylinder. Operators can simultaneously observe 360-degree line flow clarity and draw representative process samples from a single compact clamp fitting.

Size Range and Sanitary Process Applications

Source specifications list nominal sizes 1/2", 3/4", 1", 1.5", 2", 2.5", 3", and 4" for inline visual inspection and quality sampling across food, dairy, beverage, meat processing, vacuum processing, pharmaceutical, and chemical pipelines.

Material Grades and Gasket Options

Machined on CNC lathes from AISI 304 or AISI 316L stainless steel with full stainless steel fasteners, the sight glass is offered with VMQ (silicone), EPDM, Viton, or PTFE gaskets to suit varied process fluids and CIP sanitizing media (with a source-claimed tempered glass rating up to 10 bar).

Installation and Ordering Notes

Mount the unit between aligned Tri-Clover ferrules with the sampling outlet oriented downward or outward for convenient sample collection, and tighten the four tie-rod fasteners evenly during seal replacement. Specify clamp ferrule standard and any required heat numbers or MTR material certificates when ordering.
