A tree sap line connector having a fluid transfer body with interconnected walls defining a hollow inner chamber. The inner chamber is in fluid communication with a plurality of sap conduits, each of which extends from one of the walls. Each sap conduit is engageable with a sap collection line to convey sap to and from the inner chamber. At least one of the walls has a groove therein, which extends a depth into the wall and is accessible from an exterior of the fluid transfer body. The groove removably receives therein a connector piece of a sealing member. The sealing member is removably mounted to the line connector when the connector piece is received in the groove.
