What It Does and Why It Matters
The Vacurect one-piece pump mechanism creates vacuum through the movement of the outer slide tube — the pumping motion that generates negative pressure inside the cylinder. The vacuum seal in this system depends on two internal O-rings inside the slide tube remaining pliable and correctly lubricated. When these O-rings dry out — which happens naturally over time and more quickly after cleaning with soap and water — the pump loses its ability to hold vacuum consistently during the pumping stroke. The result is a device that seems to be working but fails to create enough negative pressure to produce a firm erection.
Applying 1-2 drops of Vacurect System Oil to the O-rings every 6 months restores the seal and maintains consistent vacuum performance over the lifetime of the device. The Vacurect arrives pre-lubricated from the factory — first re-oiling is typically not needed until 4-6 months after purchase, or sooner if the device is cleaned frequently with soap and water.

How to Apply
- Do not disassemble the Vacurect device — the O-rings are accessible without taking the pump apart
- Apply 1-2 drops of Vacurect System Oil directly to the O-rings within the outer slide tube
- Work the slide tube gently back and forth a few times to distribute the oil evenly across both O-rings
- Wipe away any excess oil from the exterior surfaces before use
- Re-apply every 6 months, or after any deep cleaning with soap and water that may have removed the existing oil
Vacurect Maintenance Overview
| Component | Maintenance | Product Needed |
|---|---|---|
| Internal O-rings (pump seal) | 1-2 drops silicone oil every 6 months | Vacurect System Oil (this) |
| O-ring replacement | When pump loses vacuum and oiling doesn't restore it | Vacurect O-Ring Kit + System Oil |
| Tension rings | Replace every 20-30 uses or when tension diminishes | Vacurect Tension Ring Replacement |
| Cylinder and body seal | Apply small amount before each use | Water-based personal lubricant — do not use silicone oil |
FAQs
My Vacurect isn't holding vacuum — will the system oil fix this?
If the pump is losing vacuum during use, dried-out O-rings are the most likely cause. Apply 1-2 drops of System Oil to the O-rings and work the slide tube back and forth to distribute. If vacuum performance doesn't improve after oiling, the O-rings themselves may need replacement — see the Vacurect O-Ring Kit. System Oil is required alongside the O-Ring Kit to properly lubricate replacement O-rings after installation.
Can I use any silicone oil, or does it need to be Vacurect's specific oil?
Mainspring Medical recommends pure silicone oil specifically — the Vacurect System Oil is formulated for compatibility with the O-ring materials used in the Vacurect pump. Using oils with additives or non-silicone oils risks degrading the O-ring material over time. Using the manufacturer-specified oil is the safest approach for long-term pump performance.
The Vacurect Plus Kit I bought included service oil — do I need to buy more?
Not immediately — the included 2oz bottle provides multiple years of maintenance use at 1-2 drops every 6 months. Order a replacement when your current bottle runs low, typically every 2-3 years depending on cleaning frequency.
Can I use this oil as a lubricant for the cylinder seal during therapy?
No — use water-based personal lubricant for the cylinder seal and body comfort during therapy. The System Oil is for internal O-ring maintenance only and should not be applied to the cylinder opening or tension rings.
