You may want to check with Grohe first about a replacement part.
I have a 1998 Grohe lady lux plus kitchen faucet with the pull out "hand spray" head on the spout.
The grey rubber diverter cover atop the spray head (switches it from a spray to a solid stream) is cracked.
Is this part sold by itself? could not find it online

Usually the spout is sold as a complete unit, but it may be under a "lifetime" warranty. Check with Grohe of one of its dealers.

1998 was the year they implemented lifetime warranty.
