Graco spring 119252 or 119-252. This is the spring that goes inside the 235014 dump, bypass, or prime/spray valve. I also have the o-ring for sale, it is part number 168110. This spring is no longer available from Graco. This is a brand new, OEM part.
I offer combined shipping, to do this, please add all items to your cart (instead of buy it now), and then click on your cart. Click "request total from seller" and I will send you an invoice with your total for all items plus only one shipping charge (whichever item has the highest amount is the total shipping you will pay).
If you do accidentally pay me more than one shipping charge when ordering more than one item, I will automatically refund the excess shipping when I ship your items.
