Weil Mclain 383-500-620 Maintenance Kit for Ultra Gas Boilers Sizes 155, 230, 299, and 399

I liked this kit because it came on time,with everything it said it would have in it.and it was good quality materials. I usde it for a clean and service / tune up on the Ultra boiler

Installed the kit, unit works better. Good price and fast delivery. Will buy again.

Was very disappointed when I opened the kit and it was incomplete. Reused a few pieces and got the job done.

Helps do the job well
