Usage Notes

• Depressurize the pump or system and isolate fluid‑paths before servicing the O‑ring packing.
• Inspect seating grooves, mating surfaces and hardware for wear, debris or damage before installing the new packing.
• Lightly lubricate the O‑ring with a compatible lubricant to ease installation and reduce initial wear.
• Ensure correct orientation, dimension and seating of the O‑ring to maintain full sealing capability and avoid leakage.
