Sight Glass & View Glass

A view glass is a direct visual level indicator used mainly to monitor oil level in tanks, panels, reservoirs, and vessels. It is commonly installed on hydraulic tanks, lubrication tanks, and panel reservoirs so operators can visually confirm oil level without opening the tank.

Both provide visual monitoring, but their function differs:

Sight Glass

• used in pipelines
• checks flow / presence / direction of fluid
• typically offers 360° visibility

View Glass

• used in tanks and panels
• checks level of oil/fluid in tank
• used for level monitoring, not flow

Sight glasses help:

• confirm fluid flow instantly
• detect blockage or flow interruption early
• verify process fluid presence/absence
• reduce downtime by enabling quick troubleshooting
• improve operational safety and maintenance reliability

This is especially useful in dosing lines, steam condensate lines, and process fluid pipelines.

360° visibility means the process fluid inside the sight glass can be observed from multiple angles around the body. This improves operator convenience, especially when installed in skid packages or tight plant areas where visibility from one direction is not always possible.

Petronash provides multiple material options based on service condition:

Sight Glass wetted parts

• SS316L
• Carbon Steel (CS)
• other materials on request

View Glass wetted parts

• SS316L
• other materials on request

This makes them suitable for a wide range of industrial services.

Petronash uses high quality borosilicate glass:

Sight Glass: Borosilicate glass
View Glass: Toughened Borosilicate glass

These glass types are widely preferred due to clarity and improved durability for industrial applications.

Petronash sight glasses are available in:
Connection size: 1/2” to 6”
End connection options:

• flanged
• threaded

This wide range supports multiple piping sizes in process and utility lines.

Petronash view glasses are available in:
1/2”, 3/4” and 1”
End connection:
Threaded connection

This makes them ideal for tanks, panels, and hydraulic reservoirs.

Petronash sight glasses are available in:
150#, 300# & 600# pressure rating

This makes them suitable for standard industrial pipeline services.

Petronash view glasses are designed for high-pressure tank/panel installations with:
Pressure rating up to 200 Bar(g)

This is highly useful for hydraulic systems, lubrication systems, and pressurized reservoirs.

Petronash uses PTFE sealant to:

• avoid leakage
• enhance corrosion resistance
• withstand temperature variations
• improve long-term sealing performance

PTFE sealing increases safety and reduces maintenance frequency.

Petronash provides sight and view glasses engineered for reliability and industrial performance, offering:

• direct visual flow/level indication
• 360° visibility in sight glass
• borosilicate / toughened borosilicate glass
• PTFE sealing for leak-proof performance
• multiple sizes, materials and pressure classes

These products help improve operational confidence and reduce breakdowns.

Yes. Petronash supports customization based on:

• pipeline size and connection type
• SS316L / CS / special alloy requirement
• pressure class requirement
• project standards for skid and plant integration

This ensures compatibility with EPC and industrial requirements.

Absolutely. Petronash supplies:

• sight glasses for pipelines and process skids
• view glasses for tanks and panels in hydraulic/lubrication packages

We can also provide bulk supply support for EPC and project execution requirements.
