Clamped Tie-Rod Frame and Perforated Mesh Protection Sleeve

This clamped tubular sight glass (model SSPV-22-S) encloses a replaceable tempered glass viewing tube within a perforated AISI 304/316L stainless steel mesh guard held between two Tri-Clamp ferrule end flanges by four external tie bolts. The grid-perforated sleeve shields the glass from external impacts while maintaining multi-angle flow visibility.

Series Size Range and Embedded Reference Drawing Note

The series parameter table specifies nominal sizes from 1/2" to 4" (1/2", 3/4", 1", 1.5", 2", 2.5", 3", 4"). Note that the embedded technical sheet in the series documentation shows No.50035 (DIN DN20–DN150, height H 156–240 mm) and No.50036 (SMS 1"–4", height H 156–194 mm) for the male-threaded straight sight glass series (illustrating Type A with protective net and Type B without net) rather than clamped ferrule dimensions.

Material Grades and Elastomer Seals

Available in SS304 or SS316L stainless steel with VMQ (silicone), EPDM, Viton, or PTFE gaskets for food, dairy, beverage, meat processing, vacuum, pharmaceutical, and chemical pipelines (source-claimed tempered glass rating up to 10 bar).

Pipeline Support and Ordering Notes

Align and support mating Tri-Clover piping so the glass tube is free of bending stress, and tighten the four tie rods evenly in a cross sequence after servicing. Specify at order placement if heat numbers or MTR certificates are required.
