Thank you for visiting PlumbersStock.com! Unfortunately, it will not. According to the manufacturer, this Grohe 06275SA2 membrane only works for Lady Lux, Euro Plus, and Euro Disc faucets only. The only other membrane Grohe has is the 07379SA1 that only works for Bridgeford and Lady Lux Cafe models. Your Grohe K7 single handle pull-out kitchen faucet belongs to the group that doesn't have a replacement membrane (as per manufacturer). You would need to replace the whole wand assembly, or if you are the original consumer-purchaser, you may contact Grohe at (800) 444-7643 to check if that part is covered under a warranty.
