Commercial Sink Sprayer Thread Size — The handle end thread is 7/8"-20UNEF, if you don't need the handle then the end thread is 3/4"-14UNEF. Compatible with all US-branded commercial faucets. [Before buying, please make sure that the size of the connector matches your faucet.]
Pre Rinse Sprayer — The 2023 model Pre-rinse Spray Valve has an upgraded design using a non-slip handle and a filter rubber ring to make pre-rinse tasks easier. Its powerful cleaning capability is widely used in homes, hotels, restaurants, industrial kitchens, and coffee shops.
High-Pressure Spray Valve — The flow rate can reach 1.42 GPM. The spray valve concentrates the water at one point, which improves efficiency and makes it easy to clean the sink. It can easily remove toughly baked foods and grime from dirty dishes.
Easy to Replacement — Just less than 5 minutes to remove the old one and install the new one. The nozzle is made of food-grade composite plastic, which prevents hard water and scale from accumulating and is harmless to the human body. (Tips: Make sure the gasket inside)
KANONEY Spray Valve — Pre-rinse sprayer only not includes the commercial faucet. After 1.5 million cycles of testing, it is durable and has a long service life. At the same time, we also offer 12 months replacement warranty. Any issues, please contact us from your order.
【NOTE】— Attach the pre-rinse sprayer to the hose by rotating only. The hose may be damaged if rotated. Pre-rinse sprayer only, not including the commercial faucet.
