Saybolt Viscometer Road Oil Orifice
The Saybolt Viscometer Road Oil Orifice is designed to regulate the flow of heavier-grade petroleum products during Saybolt viscosity testing. Featuring a wider calibrated opening than the Universal Orifice, it provides controlled and repeatable flow for high-viscosity materials. The threaded design allows secure installation into a Stainless Steel Viscometer Tube used with the Saybolt Viscometer.
Manufactured from durable stainless steel, the Road Oil Orifice is used when petroleum samples are too viscous for a standard Universal Orifice. It delivers accurate efflux times for heavy oils and supports reliable viscosity determinations in laboratory and industrial environments.
This orifice threads directly into compatible Saybolt Viscometer Tubes, making it an essential accessory for complete Viscometers and viscosity bath systems.
Features
- Stainless steel construction for corrosion resistance
- Wider opening for controlled flow of heavier-grade petroleum products
- Precision-machined for repeatable viscosity results
- Threaded fitting for easy installation into viscometer tubes
- Designed specifically for Road Oil viscosity testing
Applications
- Viscosity testing of heavy petroleum and road oils
- Asphalt-related fluid testing
- Laboratory and quality control testing
- High-viscosity Saybolt viscosity measurements
Standards Compliance
- AASHTO T 72
- ASTM D 88
- ASTM D 4796
Viscosity values are typically reported in Saybolt Universal Seconds (SUS) when used according to applicable standards.
Additional Information
Selection of the correct orifice, viscometer tube, and withdrawal accessories should be based on specimen viscosity and test temperature. Regular cleaning and inspection of orifices is recommended to maintain accuracy and repeatability.
The Saybolt Viscometer Road Oil Orifice integrates seamlessly with Certified MTP’s full range of Saybolt Viscometers, Brookfield Viscometers, and viscosity testing accessories.
