When an RV has one regulated exterior propane quick-connect and you want to use two compatible low-pressure appliances, the outlet fitting and each appliance hose matter. Marshall Excelsior offers the ME22YP and ME23YP two-outlet adapters. This identification guide compares their shutoff arrangements, explains what connects to each port, and shows related hoses and couplers available through UsedRVParts.
ME22YP vs ME23YP: two outlets, different shutoff arrangements
Both models are intended for a compatible low-pressure RV quick-disconnect supply, with a male quick-plug inlet and two female quick-connect outlet positions. The manufacturer distinguishes their shutoff-valve configurations.
ME22YP — Y adapter
ME23YP — Y adapter with shutoffs
Identify the Y adapters and related couplers
| Manufacturer part | Function | Important distinction |
|---|---|---|
| ME22YP | Male quick-connect to two female outlets | Y-shaped adapter; separate individual outlet shutoffs not identified in manufacturer catalog |
| ME23YP | Male quick-connect to two female outlets | Two individual manual shutoff valves, one for each branch |
| ME-GMCL-4 | Female quick coupler to 1/4-in female pipe thread | Single straight fitting, not a two-outlet Y |
| ME-GMCL-4P | Retail-packaged single quick coupler | Compare the exact part and supplied contents; not a separate Y adapter |
| MB Sturgis 401132MBS | Model 250 male quick plug to male thread | Threaded plug rather than an assembled appliance hose |
The two Marshall Y-adapter models are designed for low-pressure quick-connect applications. The manufacturer's product family also offers single couplers and hoses, each with their own pressure limits and mating connection type.
Match the hose to each appliance inlet
A MB Sturgis 100395120M dual quick-connect hose has a Model 250 male plug at the supply end and a matching female quick coupler at the appliance end. It is suited only when the appliance has the corresponding male quick-plug inlet. Its maximum rated operating pressure is 1/2 psi.
By comparison, MB Sturgis 0030448MBS has a male Model 250 quick plug at one end but finishes in a 3/8-inch female flare swivel at the other. That appliance inlet is a different design from a male quick plug. Camco 57282 is another male-to-female quick-connect extension whose profile must be matched to the specific installed fittings before use.
Do not connect a high-pressure cylinder directly to these low-pressure adapters, and do not remove an appliance's existing regulator unless its manufacturer explicitly permits a low-pressure conversion. Gas fittings and leak testing require a qualified RV propane technician.
