Tribolube 71 oxygen-compatible lubricant — 2 oz syringe
Tribolube 71 is a fluorinated polyether grease for specified equipment-service applications. The 2 oz syringe provides controlled dispensing for a trained technician applying the amount required by the component’s service procedure.
Its formulation uses non-irradiated PTFE and is intended for both stationary and moving lubrication points. Aerospace Lubricants describes compatibility with most elastomers and plastic seals, gaskets and O-rings; the exact equipment manufacturer must still approve the lubricant for the task.
Use it as a workshop consumable or in a technician’s service-support kit. An oxygen-compatible lubricant does not clean equipment for oxygen service, make an incompatible component suitable or replace the required cleaning and inspection procedures.
Keep the syringe tip clean and the container closed when not dispensing. Avoid mixing lubricants or contaminating the contents. Follow the product handling information and the equipment service instructions; internal regulator and valve lubrication is service work.
