Sanitary Sight Glass End Caps — Borosilicate & Acrylic

The borosilicate sight glass end caps are rated for a maximum operating pressure of 150 PSI. The temperature range spans from -40°C on the low end up to 400°F (500°C) on the high end, making them suitable for demanding thermal processing, CIP, and sterilization cycles.

Yes. The borosilicate glass used in these end caps complies with FDA 21CFR177.2600 and FDA 21CFR177.1550. The glass material is also approved under 3-A Sanitary Standards and carries USDA approval, making it suitable for pharmaceutical, food, dairy, and biotech applications requiring full regulatory traceability.

Borosilicate glass offers superior chemical resistance, handles extreme temperatures (-40°C to 500°C), and is approved for pharmaceutical and food-grade applications. Acrylic is lighter and impact-resistant but has lower temperature and chemical resistance thresholds. Borosilicate is preferred for CIP/SIP processes and regulated industries.

Yes. These sight glass end caps feature a seamless tri-clamp end cap ferrule design that is compatible with any standard tri-clamp line, clamp, and gasket. No special adapters are required — they integrate directly into existing sanitary piping systems of matching ferrule size.

Sanitary sight glass end caps are widely used in pharmaceutical and biotech processing, food and beverage production, USDA-regulated dairy facilities, chemical and petroleum processing, and hemp/cannabis extraction. They allow operators to visually inspect fluid flow, color, and consistency without breaking process containment.

The body and ferrule are constructed from 316 stainless steel, a pharmaceutical-grade alloy known for its excellent corrosion resistance, durability, and compatibility with aggressive cleaning agents used in CIP and SIP protocols. The glass insert is pharmaceutical-grade borosilicate for chemical and thermal resistance.
