All fittings on ELEY hose reels are made from lead-free brass, machined with the standard 3/4-inch Garden Hose Threads (GHT), which is the universal threads used on the fittings of most garden hose and watering tools sold in the United States and Canada. Even though the inside diameter of any brand of garden hose might be 1/2, 5/8, or 3/4-inch, the fitting on the ends will always be 3/4-inch GHT.
No Aluminum Fittings! Avoid attaching any aluminum fitting to brass when possible due to galvanic corrosion. They will likely weld or fuse together over time and you may not be able to separate them. We recommend brass, nickel-plated or stainless steel fittings. Lead-free brass delivers the best results.
GHT is not NPT Please note that GHT is not compatible with NPT (National Pipe Thread), which is typically found on most steel and brass pipe fittings. So remember, 3/4-inch GHT is not the same as 3/4-inch NPT.
