Gallagher Fluid Seals helps meters & instruments manufacturer through the design and fabrication of a custom-molded gasket with an engineered profile.
Our client’s micro corrector was experiencing water intrusion past the gasket, caused by improper seal material and configuration.
Gallagher Applications Engineer Benjamin Mell worked closely with our client to identify & address the issue and suggested sending a sample of the instrument to GFS headquarters. Our engineering team received the hardware and investigated the root cause of the seal failure.
GFS engineers observed that our client’s closed-cell foam gasket had taken a severe compression set. This was limiting the life & effectiveness of the foam seal, which in turn allowed water to penetrate the instrument and damage the electronics.
Based on our experience and industry insights, GFS was contracted to design & fabricate a custom-molded gasket with an engineered profile to properly mate with the hardware and perform to customer expectations/ requirements. (see Figure 1. red seal)
Results / Next Steps
The Gallagher-engineered gasket solution was a success; it eliminated water intrusion and damage to the electronics, reduced warranty claims, and provided a more reliable product.
With the success of this project, GFS is partnering with our client for additional custom solutions. Next, we plan to help design and fabricate a window seal on the micro corrector to further decrease the possibility of water intrusion.

DuPont™ Kalrez® – Total Cost of Ownership Analysis
The drive to reduce costs and environmental concerns have caused many design and processing engineers to turn to perfluoroelastomer sealing parts as the most cost-effective sealing solutions. The value-in-use of perfluoroelastomer can be proven in operating conditions where conventional elastomers fail. Even under less arduous conditions, DuPont Kalrez perfluoroelastomer seals can be the best solution, as they can last significantly longer than conventional sealing solutions.
Economics depend on the total system cost
When considering the economics of elastomeric seals, it is vital to look beyond the total cost related to the sealing solution. The total system cost in use is the sum of the cost of the O-ring seal plus the installation cost plus the downtime cost (including loss of productivity through leakage and clean-up costs).
