Just replaced o rings in kitchen faucet but where do I put the silicone grease? Thanks

Loosen the central nut

remove the handle that turns water on and off , usually an allen wrench lift and swing back and forth at the same time. the spigot should come off. replace o rings lubricate with silicone grease reinstall spigot and handle

The base of spout is like a nut unscrew then lift off spout install new o-rings be sure to use plumbers grease or vaseline to coat new o-ring ,reinstall as was disassembled that should take care of problem.You may need a strap wrench to remove spout base nut.

not difficult to take apart, but might be difficult for you to put back together...

lots of steps to repairing the faucet, might be best to call a handyman in your area.
there are several items that need to be replaced, including the O-Rings for the spout (the reason it is difficult to move from left to right), the diverter, the cartridge.
everything needs to be cleaned and greased with non silicone faucet lubricant, not vasoline!

we can run you through the steps if you are brave enough to try and repair. otherwise, I would call a handy man, he can have this fixed in about 20 minutes time.

I may be able to help you. Some faucets are made with the option to have a base or to mount directly to the counter.The bigger washer might be the one that seals the faucet to the counter The leak out of the top of the faucet is probably caused from the plastic nut with the grooves in the top of it not being tight enough. The repair kit should have came with a tool that has a allen wrench on one end and two prongs on the other.Use the pronged end to tighten the plastic nut ,If the other parts where put in correctly this should cure your problem. If the faucet continues to leak you can get a pamplet that will give you instructions from a rep at the plumbing supply or on line in one of the sights for Delta Faucets.

o-rings in the spout need to be greased or replaced...use silicon grease if you are greasing them....not petroleum based product.

You will need someone to help you hold faucet body and assembly to sink, so that you can tighten up rod from under sink without it getting bound.

Rebuild kits are available but just remove the spout, clean the inside with scotch brite and put a THIN coat of food grade silicon grease or vaseline on the 'O' rings.

There are "o" rings in the area where it is leaking. You can get them at almost every hardware chain. Clean everything well with scotchbrite ant put silicon grease on before you put it back together.

The o-ring(s) is expanded or stuck. Try spraying silicone lub (found it at most discount ro hardware stores)  Keep twisting it back and forth as you raise it up . Yes. You may have to force it up which will tear the old o-rings that you are going to replace anyway.
