Sunnen Products Company, a global leader in high-precision bore finishing and measurement, has launched MB-30LO, its latest honing oil engineered for general-purpose metalworking and critical HVACR 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 HVACR system servicing and fabrication.
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 HVACR technicians and simplifies handling requirements.
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 HVACR 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 HVACR manufacturing.
The oil’s viscosity of 26cSt (at 40°C) guarantees optimal lubrication and outstanding results in both honing and cutting operations for HVACR tubing and fittings. With a five-year shelf life when sealed and stored properly, contractors benefit from long storage potential without quality loss.
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 HVACR 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 HVACR shops.
Sunnen’s improved formulation incorporates reduced odour-causing ingredients, further enhancing the workplace environment while maintaining top-tier performance for HVACR applications. For post-honing cleanliness, HVACR components are best cleaned with aqueous detergent, supporting process quality from start to finish.
Made in the USA, MB-30LO is available in Australia.
