OverviewIdeal Disposable Hypodermic Needles with aluminum hard hub are single-use needles designed for livestock vaccination and medication injection. The 16 gauge x 1-1/2" size is the longest in the 16 gauge lineup — combining the maximum flow rate of a 16 gauge bore with a 1-1/2" length that provides sufficient depth for intramuscular (IM) injections in cattle and horses. This combination makes it the go-to choice when administering highly viscous products via the IM route — such as thick antibiotic suspensions, oil-adjuvanted vaccines requiring IM delivery, and iron dextran in larger animals — where both bore size and needle depth are critical for proper placement and product delivery. The hard aluminum hub provides a rigid, secure connection to standard luer-lock and luer-slip syringes, and the sharp bevel ensures clean penetration with minimal tissue trauma.Key Features 16 gauge x 1-1/2" — large bore, full-depth IM needle for cattle and horses 16 gauge bore delivers maximum flow rate for viscous, oil-adjuvanted, and suspension formulations 1-1/2" length provides sufficient depth for intramuscular injection in large animals Ideal for IM delivery of thick antibiotic suspensions and viscous products requiring deep muscle placement Hard aluminum hub for a rigid, secure connection to luer-lock and luer-slip syringes Sharp bevel for clean, consistent penetration and minimal tissue trauma Single-use disposable design maintains sharpness and hygiene for every injection Compatible with standard veterinary syringes and automatic vaccinators Specifications Brand: Ideal Gauge: 16 ga Length: 1-1/2" (1.5") Hub Material: Aluminum (Hard) Type: Disposable Hypodermic Needle Species: Cattle, horses, swine Best For Intramuscular (IM) administration of thick antibiotic suspensions in beef and dairy cattle IM delivery of oil-adjuvanted vaccines requiring deep muscle placement in large animals Iron dextran and other high-viscosity IM products in cattle and horses Operations needing a large-bore, full-depth IM needle for viscous product delivery in large livestock
