Maximum IM Reach — 21G x 2” for Deep Muscle Administration
The Terumo Hypodermic Needle 21G x 2” is engineered for deep intramuscular delivery, combining a 21-gauge (0.8 mm) diameter with an extended 50 mm (2”) length. The green ISO colour-coded hub provides instant gauge identification, while the precision tip and silicone coating ensure smooth, confident insertion even at depth.
Built with Terumo’s thin-walled technology, this needle is the preferred choice for large muscle group injections where maximum reach is required. The semi-transparent hub confirms placement via clear flashback, and the short bevel minimises tissue trauma throughout the full insertion depth.

FAQs
When is a 2” needle preferred over 1.5” for IM injections?
The 2” length is recommended for patients with higher BMI or when targeting deeper muscle groups such as the gluteus maximus, where a 1.5” needle may not reliably reach muscle tissue.
Does the 21G bore handle standard IM medications well?
Yes — 21G provides adequate flow for most IM medications including vaccines, antibiotics, and hormones.
Is the green hub ISO 6009 compliant?
Yes — green is the internationally standardised colour code for 21G needles.
Does the thin-wall design maintain strength at 2” length?
Yes — Terumo’s manufacturing process ensures structural integrity and consistent bevel sharpness across all lengths.
Is it compatible with all standard syringes?
Yes — fits all Luer Lock and Luer Slip syringes.
