What size syringe needle should I use for injecting epoxy into connectors?
Most common connectors are machined to accept buffer tubes of 0.9mm (900um, or 0.036”) diameter. Thus, it is recommended to use similar diameter syringe needle for epoxy injection: a 20 gauge syringe tube is approximately 0.9mm / 0.036” in OD, and is recommended for most common connector types.
(note: if your particular connector is not designed to accept 900um buffer tubes, you’ll need to discuss proper syringe gauge size with your connector supplier).
