Description
The Thin Wall needle is thinner than a Regular Wall needle. The inner diameter is bigger without any increase in the outside diameter. For example, a 21g Thin Wall needle has the same outside diameter as a 21g Regular Wall, but has the same inner diameter as a 20g needle. Thin Wall allows the same flow volume as a Regular Wall needle one gauge larger. Thin Wall is available in 18, 19, 21, 22, and 23 gauge sizes.
