In industries where sealing performance is critical, quality cannot be left to chance. Whether a gasket is being used in automotive systems, industrial equipment, fluid handling assemblies, or heavy machinery, manufacturers and OEMs need confidence that every component will perform consistently under real-world conditions. That is where PPAP approval plays a vital role.
Dobson Gaskets has been recognised on a global stage, earning the prestigious Supplier Excellence Recognition Award from Caterpillar Worldwide, a distinction that places the company among the very best in an extensive international supply network.
PTFE is often specified as a default sealing material for chemically aggressive environments. However, in practical engineering terms, PTFE is not a single material. Virgin PTFE, filled PTFE, and expanded PTFE (ePTFE) exhibit fundamentally different mechanical behaviours, particularly under load, over time.
Hydraulic systems depend on a simple principle: contain pressurised fluid reliably and consistently. When sealing fails, performance drops, safety risks increase, and downtime becomes costly. One of the most overlooked causes of hydraulic system sealing failure is a change in hydraulic oil specification.
In 2001, Daniel O’Neill returned to Dobson Gaskets after a brief spell away, and he has been here ever since. Now celebrating 25 years with the company, Danny’s journey reflects not just the evolution of gasket manufacturing, but the blend of traditional skill, innovation and family culture that defines Dobson Gaskets today.
