PVC Nipple, 1x3

Compact but tough, the American Granby 1" x 3" PVC Nipple is a Schedule 80 threaded fitting that earns its place in nearly every water-treatment toolkit. The 1-inch size suits the larger plumbing runs common to whole-house softeners, filtration tanks, and well systems, while the short 3-inch length makes it ideal for tight connections between adjacent components where a longer nipple simply will not fit.

• Schedule 80 (SCH80) PVC for added wall thickness and strength
• 1" nominal diameter with a 3" overall length
• Male-threaded both ends for joining female-threaded fittings
• Resists corrosion, scale, and aggressive water chemistry
• Suited to softener, RO, and well-pump plumbing
• Featherweight at roughly 0.09 lbs each

Schedule 80 PVC is the heavier-duty cousin of standard Schedule 40, offering greater durability for threaded joints that see repeated assembly or sustained pressure. That makes this nipple a smart pick for bypass arrangements, valve nipples, and manifold buildouts where a metal fitting might eventually corrode or seize. Unlike brass or galvanized parts, it will never contribute rust or metallic taste to the water, which is a meaningful benefit on the treated side of a filtration system.

Installation is straightforward. Wrap the male threads with PTFE tape or apply a quality thread sealant, then tighten by hand and finish with a gentle wrench turn. Avoid over-tightening, as plastic threads can split under excessive force, and back off slightly if you feel resistance building too quickly. The short close-coupled length is perfect for joining two female fittings nose to nose, a frequent need when assembling control-valve plumbing, drain connections, and tank manifolds. With its corrosion resistance, reliable sealing, and economical nature, the American Granby 1" x 3" SCH80 PVC nipple is a dependable fitting for new installations and repairs alike across residential and light commercial water systems.

Stocking a small assortment of common nipple sizes keeps installations and repairs moving without a trip to the supply house, and this 1-inch close nipple is one of the most frequently reached-for lengths. Combined with matching SCH80 couplings, tees, and adapters, it helps you build clean, corrosion-free plumbing that stands up to the rigors of water-treatment service. Dependable and economical, it is the sort of everyday fitting that quietly earns its keep on installation after installation.
