Samson 27 Gal Waste Oil Suction Unit #3726
The Samson 3726 is a mobile 27-gallon waste oil suction unit designed for extracting used oil directly through a vehicle's dipstick tube. Its compressed-air-powered Venturi system creates vacuum inside the steel reservoir, allowing the unit to operate remotely after vacuum has been established.
Designed for service shops, quick-lube operations, fleets and vehicle maintenance facilities, the 3726 provides a convenient alternative to gravity draining when access through the dipstick tube is appropriate. Once collected, used oil is discharged through the hose by safely pressurizing the reservoir according to Samson's operating procedure.
Product Features
- 27-gallon / 100-liter mobile steel reservoir
- Venturi vacuum system powered by shop compressed air

- Approximate 2 minute 30 second full-vacuum time
- 42-liter effective suction volume after a complete vacuum cycle
- Vacuum gauge provides visual indication of operating vacuum
- Pressure discharge through the unit's discharge hose
- Maximum reservoir discharge pressure of 0.5 bar
- Mobile configuration for movement between service bays
- Includes Samson 8-piece wand / probe kit
How the Suction System Works
Close the suction and discharge valves and use the unit's compressed-air vacuum system to evacuate the reservoir. Samson specifies approximately 2 minutes 30 seconds to reach a complete vacuum. Once sufficient vacuum is established, the appropriate probe or connector is inserted through the vehicle's dipstick tube so that it reaches the lowest point of the crankcase.
Opening the suction valve allows used oil to flow into the reservoir. Samson specifies an effective suction volume of approximately 42 liters following a complete vacuum cycle.
Pressure Discharge
The 3726 uses pressure discharge to empty the reservoir. Samson instructs the operator to connect compressed air to the charge valve using a tire inflator, pressurize the container to 0.5 bar maximum, and open the discharge-hose valve.
Published Suction Performance
| Ø5 mm Probe | 2.0 L/min |
| Ø8 mm Probe | 4.1 L/min |
| Mercedes Probe | 7.1 L/min |
Samson publishes these rates using SAE 30 oil at 80°C. Actual extraction time varies with oil temperature, viscosity, probe diameter and vehicle configuration.
Included Wand & Probe Kit
Samson's current catalog lists the 3726 with an 8-piece wand kit. Service documentation identifies the probe system as including VAG and Peugeot connectors along with metallic and flexible suction probes in multiple diameters and lengths.
A Mercedes connector, Samson #737957, is listed separately in the service manual for applications requiring that connection.
