Weight. From the Manufacturer Grohe Quick Coupling (Yellow) # 46 138 000. Review: Great Replacement to Increase Flow - This was a perfect replacement for the quick coupling that was in our Grohe Ashford faucet / flexible hose. The faucet is a 2016 faucet that never flowed that great. When the faucet put out a small stream, I finally pinned it down to as blockage in the restriction valve and backflow valve which was rated at 1.75 GPM. I cleared it out with compressed air so that it was back to the original flow which was still a slow rate of flow. After replacing it with this fitting which doesn't have the restriction, we're getting great flow; it doesn't take forever to fill up a coffee pot. Review: Review - OEM part works great after the old one formed a crack and leaked after 25 years. I was afraid to get another brand, so i bought original. Easily installed and i expect another 25 years. ## Features - 1/2 in. and 0.12 lbs. weight - 2.2 gpm - Faucet Spout Quick Coupling - Model number: 46138000 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003FZAFOI | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #128,824 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,415 in Faucet Parts #1,792 in Pipe Fittings | | Color | StarLight Chrome | | Customer Reviews | 4.6 4.6 out of 5 stars (649) | | Date First Available | January 12, 2006 | | Finish | No Finish | | Included Components | Coupling | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.811 ounces | | Item model number | 46138000 | | Manufacturer | Grohe | | Material | Metal | | Mounting Type | Face Mount | | Number Of Pieces | 3 | | Part Number | 46138000 | | Product Dimensions | 4.8 x 3.6 x 1.4 inches | | Size | one-size | | Usage | Inside | | Warranty Description | “*1 year Limited warranty from date of purchase” | ## Images ![46138000 1/2 in.
