Brass Short Shank Type Fitting, 0.50 Inch Hose ID to 3/4-11-1/2 Male Garden Hose (NPSH), Straight

Short shank fittings rely heavily on proper clamp selection and placement to hold securely. The barbed shank is sized for a 0.50-inch hose ID, so the fit itself is correct for that hose size. What affects holding strength is how many clamps you use, where they sit on the shank, and whether the clamp type matches your hose construction. Get that right and you won't have slippage problems in low pressure suction or discharge service.
