Factory Direct Supply 45 Degree Elbow Fittings with Multiple Size Options Available

We’ve been running these 45-degree elbows for a while now, and they hold up pretty well under pressure—typically 100 to 300 KPa depending on your setup. flow rate usually sits around 40 to 120 L/h, which is fine for most drip lines or micro-spray systems. Sizes range from L20 up to L110, so you can match them to whatever pipe you’re working with. The black oxide surface treatment isn’t just for looks; it actually helps with scratch resistance in those tight spots where fittings rub against gravel or concrete. Most buyers go with the L25 or L32 for standard garden greenhouse work, but the L63 and L75 are better for larger urban greenbelt layouts. Actually, the nozzle diameter is 0.8 to 1.2 mm, and the spray diameter hits 1.0 to 4.0 meters—so it’s not ideal for high-pressure industiral stuff, more for controlled irrigation.

These are female-threaded connections in blue plastic, and they use a GB standard, so they’re compatble with most Chinese-sourced pipework. We usually have stock on the L20 through L50 sizes, but the L90 and L110 can take 20 days or so to ship—check lead time on those. The working pressure isn’t super tight; it’s more of a range, 100 to 300 KPa, which basically means they’re fine for gravity-fed or low-pressure pump systems. 3. The leak-proof design comes form the round head type and the pressure-type power source—what it does is create a seal when the system is pressurized, so no drips or waste. We’ve seen these used in flower cultivation setups where consistent moisture is critical, and they do the job without much fuss. Also, the tenacity is better than reagent-grade fittings for this, because the plastic doesn’t get brittle under UV exposure over a season or two.

One thing a buyer might not think to ask: the spray diameter changes a lot with teh nozzle diameter, so if you’re using the 0.8 mm nozzles, you’ll get a tighter, more targeted stream—good for potted plants—but the 1.2 mm gives a wider, softer spray for larger beds. The color is blue, which helps with quick visual identification in a tangled hose setup. Anyway, ordering options are pretty straightforward—our company can do single sizes or mix them in a box, but the MOQ varies by size; for L20 to L40 it’s usually 100 pieces or so, while L90 and L110 might need a minimum of 50. Roughly, lead time is 7 to 14 days for in-stock sizes, but confirm availability if you need a rush.
