The best choice depends on the system: the Alemite 4-way evacuation valve is the closest match for a dedicated evacuation-valve replacement, while the CPS and VIVOHOME manifold sets suit HVAC or automotive service tasks. The Summit Hydraulics valves are flow diverters, and the Swimline part is a pool-filter valve, so they are not substitutes for refrigerant evacuation equipment. Compare the listed applications before choosing.
| Product | Best suited for | Key detail |
|---|---|---|
| Alemite 4-Way Evac Valve | Dedicated evacuation-valve replacement | 1-inch NPT connection |
| CPS 4-Valve Manifold | HVAC refrigerant service | Five-foot hoses; listed refrigerants include R-134a and R-410A |
| VIVOHOME Manifold Gauge Set | Automotive A/C diagnostics and service | Four hoses; compatible with A1 and A2L refrigerants per listing |
| Summit Hydraulics 32 GPM Valve | Hydraulic flow diversion | 32 GPM nominal flow |
| Swimline Pool 4-Way Valve | Specified Hydrotools filter systems | Replacement part for listed models |
Alemite 4-Way Evacuation Valve
The Alemite 340289-1 is the closest product match for someone searching specifically for a 4-way evacuation valve. Its listed connection is 1-inch NPT. The product information also identifies a 340289-2 model with a 1.5-inch NPT connection, which makes connection sizing an important selection check.
- Best for: Buyers replacing or sourcing an Alemite-style evacuation valve who need the listed 1-inch NPT version.
- Why it was selected: Its product name directly identifies it as a 4-way evacuation valve.
- Check before buying: Confirm the required NPT size and model. The supplied information does not specify broader system compatibility.
CPS Four-Valve Manifold With Hoses
This CPS manifold is an HVAC service tool rather than a single replacement evacuation valve. The listing describes Vortech vacuum valves, 3-1/8-inch Class 1.0 gauges, and five-foot hoses. It lists compatibility with R-134a, R-22, R-404A, and R-410A.
- Best for: HVAC technicians or informed buyers who need a four-valve manifold for refrigerant service and evacuation-related work.
- Why it was selected: Its vacuum-valve and manifold features make it relevant to evacuation tool searches.
- Check before buying: Verify the refrigerant and connection requirements of the specific system. The listing dimensions alone do not establish fit.
VIVOHOME Four-Valve Manifold Gauge Set
The VIVOHOME set is presented for automotive A/C diagnostics, charging, and evacuation. It includes four color-coded, five-foot hoses, an aluminum manifold body, brass fittings, and an unloading valve. The listing states that the set is compatible with A1 and A2L refrigerants and names R-134a, R-410a, R-22, and R-32.
- Best for: Buyers seeking a multi-hose automotive A/C manifold for pressure readings and service tasks.
- Why it was selected: It explicitly includes evacuation use and four-valve manifold equipment.
- Check before buying: Listed hose working pressure is 800 psi. Confirm service requirements and refrigerant compatibility before use.
Summit Hydraulics 32 GPM Diverter Valve
This Summit Hydraulics product is a four-way rotary flow diverter, not an HVAC evacuation valve. It has a closed-center design, a listed nominal flow of 32 GPM, a maximum pressure of 4,640 PSI, and #12 SAE ports.
- Best for: Hydraulic applications that need a four-way diverter meeting the listed flow and pressure specifications.
- Why it was selected: It is a four-way valve, but its stated function is hydraulic flow diversion.
- Check before buying: Avoid this if you need a refrigerant evacuation valve or manifold; its application and ports are hydraulic.
Swimline Pool Filter Four-Way Valve
The Swimline valve is an OEM-style replacement part for certain Hydrotools pool systems. The listing names models 71223, 71225, 71233, 71400, 71405, 71405T, and 71423. It is unrelated to HVAC evacuation despite having “4-way” in its name.
- Best for: Pool owners maintaining one of the specifically listed Hydrotools systems.
- Why it was selected: It is a four-way replacement valve, but for a pool-filter application.
- Check before buying: Match the pool system model carefully; do not select it for refrigerant or hydraulic service.
Buying Guide: How To Choose A 4-Way Valve
Do you need a valve or a manifold tool?
A replacement valve is a component matched to a particular system and connection. A manifold gauge set is a service tool with gauges, hoses, and valves used to monitor and manage system connections during service. The Alemite product is described as an evacuation valve; CPS and VIVOHOME are manifold sets.
Which application does the valve serve?
Identify whether the job involves refrigerant equipment, hydraulic machinery, or a pool filter. “Four-way” describes a valve arrangement, not a universal application. A hydraulic diverter or pool replacement valve is not a substitute for HVAC evacuation equipment.
What specifications should you compare?
- For replacement valves, confirm model number, connection type, and connection size.
- For refrigerant manifolds, check listed refrigerant compatibility, hose length, gauge details, and the service task.
- For hydraulic valves, compare nominal flow, maximum pressure, port type, and center design.
- For pool valves, confirm the exact filter or system model.
Should you prioritize flow, pressure, or compatibility?
Use the specification that matches the system. Hydraulic buyers should compare flow and pressure ratings. HVAC buyers should verify refrigerant and tool requirements. Replacement-part buyers should prioritize the original system’s model and connection dimensions. Do not infer compatibility from a shared “4-way” label.
Frequently Asked Questions
What is a 4-way evacuation valve?
It is a valve identified for evacuation-related use, but the exact function and fit depend on its design and system. The Alemite listing is the product here explicitly named a 4-way evacuation valve.
Is a four-valve manifold the same as a four-way valve?
No. A four-valve manifold is a service tool with multiple valves and connections. A four-way valve is a valve component or flow-control arrangement. Check the product’s stated application.
Can a hydraulic diverter valve be used for HVAC evacuation?
The listed Summit Hydraulics products are hydraulic flow diverters. Their product information does not identify them for refrigerant service, so they should not be treated as HVAC evacuation valves.
How do I choose between the two Alemite connection sizes?
Match the required connection size. The supplied information lists the 340289-1 with 1-inch NPT and the 340289-2 with 1.5-inch NPT.
Is the Swimline four-way valve for air conditioning?
No. The listing identifies it as a pool-system replacement part for specified Hydrotools models.
