Sunnen Products Company, a global pioneer in high-precision bore finishing and measurement, proudly announces the launch of MB-30LO, its latest honing oil engineered for general-purpose metalworking and critical HVAC/R applications.
As a versatile metalworking oil, it supports a broad range of machining processes, including drilling, tapping, reaming, and screw machines, alongside its superior honing performance for HVAC/R system servicing and fabrication.
MB-30LO
MB-30LO stands apart from traditional solutions by offering a significantly milder scent versus the original MB-30, ensuring improved operator comfort in confined HVAC/R workspaces during system servicing and fabrication.
The oil features ultra-low VOC content measuring ≤50g/L and is fully compliant with ASTM1868-10 and SCAQMD standards, delivering safer air quality and meeting strict environmental regulations. Not classified as hazardous under OSHA 2012, MB-30LO enhances workplace safety for HVAC/R technicians and simplifies handling requirements.
New honing oil
The new honing oil is easily identifiable thanks to its distinctive dark brown/amber appearance
The new honing oil is easily identifiable thanks to its distinctive dark brown/amber appearance. A high flash point above 110°C significantly reduces fire hazards when working near electrical panels and heat sources typical in HVAC/R system installation and repair.
A specific gravity of 0.92 (at 60°F) provides predictable performance and system compatibility in precision pipe honing and fabrication commonly required in HVAC/R manufacturing.
The oil’s viscosity of 26cSt (at 40°C) guarantees optimal lubrication and outstanding results in both honing and cutting operations for HVAC/R tubing and fittings. With a five-year shelf life when sealed and stored properly, contractors benefit from long storage potential without quality loss.
Seamless integration
Designed for seamless integration, MB-30LO is drop-in compatible with MB-30, LT9X, SHO965, and LP8X, allowing direct addition or mixing for an easy upgrade and transition in existing HVAC/R maintenance setups. MB-30LO can also be used to top off machines already running MB-30, eliminating the necessity of a full system flush and simplifying adoption for HVAC/R shops.
Sunnen’s improved formulation incorporates reduced odor-causing ingredients, further enhancing the workplace environment, while maintaining top-tier performance for HVAC/R applications. For post-honing cleanliness, HVAC/R components are best cleaned with aqueous detergent, supporting process quality from start to finish.
Made in the USA
Proudly made in the USA, MB-30LO supports domestic manufacturing preferences and supply chain reliability for domestic sourcing among U.S. HVAC/R contractors and facility operators.
With these cumulative advantages, Sunnen’s MB-30LO continues the legacy of innovation and reliability essential to modern metalworking and precision HVAC/R manufacturing.
