Banjo RN100-075 Polypropylene Reducing Nipple

A compact reducer that joins 1-inch and 3/4-inch female threaded fittings in a sprayer or plumbing run.

Join two thread sizes cleanly

When two parts of a sprayer line almost fit, this is the small piece that makes the connection make sense. The Banjo RN100-075 steps from a 1-inch male pipe thread to a 3/4-inch male pipe thread, so it can join two female threaded fittings with different openings. Use it when a tank outlet, valve, manifold, or other threaded component needs to meet a smaller line connection. Check the thread size on both parts before ordering. A reducer cannot correct the wrong thread style, a damaged fitting, or a hose end that needs a barb instead.

A practical part to keep nearby

Sprayer plumbing gets changed a fitting at a time. You replace a valve, move a gauge, or adapt a line to a different pump, and suddenly the parts on the bench do not share a size. Keeping a reducing nipple with the repair pieces can save a second trip and get the plumbing back together while the tank is empty. This part is short and direct: male threads on both ends, with a shoulder between them for a wrench. The larger end is 1 inch MPT; the smaller end is 3/4 inch MPT. Those dimensions matter more than the outside appearance, so compare the existing parts or check their markings before you thread anything together.

Built for working plumbing

The fitting is glass-reinforced polypropylene, with chemical resistance for use in compatible spraying and plumbing systems. That makes it a useful choice where a metal fitting is not the right match. Confirm the chemicals in your system and the requirements of the surrounding components before installation. The fitting does not set the pressure rating for a complete assembly; the pump, hose, valves, seals, and every connected part still need to suit the job.

Install with care

Start both sides by hand. The threads should engage without binding. If they do not, stop and check size, thread condition, and alignment rather than forcing the fitting. Use the thread sealant and tightening method required by your sprayer setup. Avoid leaning hard on a plastic fitting with a long wrench. Tighten enough to seal while supporting the adjoining parts, then inspect for leaks during a controlled test before returning the system to work. Replace a cracked or cross-threaded part instead of trying to make it hold.

Before you put the sprayer away

A plumbing repair is easier to repeat when the part number is written down. RN100-075 identifies this size combination for the next maintenance round. Rinse the sprayer using the directions for the product you used, and check threaded connections when hoses or pumps are removed. If your setup needs a different material, thread size, or connection type, measure first. A few minutes with the old fitting in hand beats rebuilding the line twice.

Directions for use

Install between compatible female threaded fittings. Start threads by hand and stop if they bind. Use the thread sealant and tightening method required by the sprayer system. Test the completed connection for leaks before use.

Cautions

Confirm thread sizes and chemical compatibility before installation. Do not force crossed or damaged threads. System pressure suitability depends on every connected component.
