The Gusmer Graco 1523/1524-88 seal kit is associated with legacy Gusmer H-20/35 series spray foam proportioners and hydraulic proportioning systems widely used throughout the spray foam insulation industry. These systems became well known for rugged hydraulic performance, long service life, and dependable material processing in demanding field applications.
The 1523/1524-88 configuration is commonly referenced for maintenance and rebuild applications involving older Gusmer hydraulic equipment, including seal replacement and fluid system servicing. Proper maintenance of hydraulic and proportioning components is critical for maintaining balanced pressure, preventing leaks, and ensuring consistent spray performance.
Although newer Graco Gusmer systems such as the GH-2 and GH-4 are now available, many contractors continue operating legacy Gusmer H-series proportioners due to their durability and proven reliability. As a result, demand remains strong for OEM replacement seal kits, rebuild components, and maintenance parts supporting these classic hydraulic spray foam machines.
SPF Depot supplies OEM and replacement components for legacy Gusmer and Graco spray foam equipment, including seal kits, rebuild parts, packings, O-rings, hydraulic components, and proportioner maintenance items. Maintaining older proportioners with quality replacement parts helps extend equipment life while reducing costly downtime in the field.
