Below is a list of Hypodermic Tubing manufacturers from Wellsboro, Pennsylvania. Hypodermic tubing is commonly used as the medium for introducing medicine or drugs under skin. Either as a method of injection or removal, hypodermic tubing allows for the rapid delivery of fluids. As a result, this type of stainless steel tubing is usually formed into hypodermic needles for medical applications. It is a slender, hollow, cylindrical length of stainless steel, typically 316 or 304 grade, with a puncturing point made at one end to form a needle.
