QUESTION: What size syringe needle should I use for injecting epoxy into connectors?
ANSWER:
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).
