Collection: 412H, 612MB & GLV 3.0 Parts

Do you stock OEM parts or aftermarket?

Both. Our catalog includes OEM parts for the pump families we service most heavily, and high-quality aftermarket alternatives where they meet or exceed OEM specifications. On rebuilds, any part replaced is either OEM or an equivalent-spec aftermarket part — we do not use undersized or out-of-tolerance components.

For general questions about GLV, see our main FAQ.
