FREQUENTLY ASKED QUESTIONS

When should I replace the O-rings?

Replace them whenever you notice fluid seepage between tip and base, and as preventive maintenance after intensive use or exposure to aggressive solvents. Keeping a spare kit avoids downtime.

Are these seals compatible with sealed coaxial needles?

No — sealed coaxial needles are laser-welded and have no serviceable seals. This kit is for the modular coaxial needle bases and tips.
