Cross-References & Interchange
Replacing another brand's 1 in. 600 WOG locking brass ball valve? Match nominal size, end connections, and WOG rating for a direct fit — or send us your part number and we will confirm the interchange. Need a male thread on one end? See the 1 in. MxF locking-handle ball valve (948174L). Don't need the locking handle? The standard 1 in. 600 WOG full-port ball valve (940175) is the same valve with a conventional lever.
