Begin with a thorough inspection of all involved surfaces:shaft sealing surface and housing bore, seal lip(s), and outside diameter. Maintaining the integrity of the sealing lips is “Priority 1″. The slightest tear or nick can develop into a more significant issue during operation.

Another benefit of neoprene foam gaskets is their versatility. These gaskets are available in a variety of shapes, sizes, and thicknesses to meet the specific requirements of different applications. Whether it's a simple O-ring seal or a complex custom gasket design, neoprene foam gaskets can be tailored to fit the unique needs of various industries.
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
