Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the assembly, which can compress the O-ring beyond its elastic limit, leading to permanent deformation and seal failure.Adhere to specified torque values for fasteners and ensure the gland design allows for proper compression without overstressing the O-ring.
Using incompatible lubricants or cleaning agents that degrade the Buna-N material.Consult material compatibility charts to select lubricants and cleaning agents suitable for Buna-N and the specific application environment.

Common Applications

  • Hydraulic and Pneumatic Systems
  • Automotive Fuel and Oil Systems
  • Industrial Machinery and Equipment

⚠️ Engineering Warnings

  • Not suitable for applications involving strong acids, ketones, or esters.
  • Operating temperature range for Buna-N should be strictly observed to maintain sealing integrity.
