690291041501

The barcode 690291041501 corresponds to a product reported as "GRINNELL CORP. 1/2X4 BLACK NIPPLE." However, it seems there may be some confusion regarding the description provided. Grinnell Corp is primarily known for its manufacturing of plumbing and mechanical products. The term "nipple" in plumbing refers to a short piece of pipe, typically with male threads on both ends, used to connect two other fittings.

In the context of the product name, "1/2X4 BLACK NIPPLE" likely refers to a plumbing component—a black iron or steel nipple that is 1/2 inch in diameter and 4 inches long, used in various plumbing applications.

Unfortunately, I could not locate specific pricing information or detailed specifications for this exact product. Additionally, there do not appear to be any specific warnings associated with the product. However, as with all plumbing products, it is essential to follow proper installation guidelines and safety practices to ensure functionality and safety.

If you require further information about this product or its applications, please refer to plumbing supply retailers or the manufacturer's resources.
