Vacurect Silicone Oil — VED Pump O-Ring Lubricant

By Bonro / Vacurect

Light Silicone O-Ring Lubricant  |  For Vacurect & Other VED Pump Brands  |  Prevents Vacuum Loss from Dry O-Rings  |  Apply After Each Soap-and-Water Cleaning  |  For Pump Use Only — Not a Personal Lubricant

Important: This silicone oil is for the pump mechanism only. Apply only to the pump's O-rings. Do not use this oil as a personal lubricant on tension rings or for direct personal use — it is a mechanical lubricant, not a body lubricant. A separate water-soluble personal lubricant is needed for tension ring use and personal comfort during therapy.

Vacurect Silicone Oil is the recommended maintenance lubricant for Bonro Vacurect vacuum erection device (VED) pumps and other brands of ED vacuum pumps that require periodic O-ring lubrication. The two O-rings housed within the outer slide tube of the Vacurect pump create the sliding vacuum seal that allows the tube to move and maintain negative pressure during use. These O-rings must remain pliable and lubricated to maintain a consistent vacuum. Regular cleaning of the pump with mild soap and water — as recommended for hygiene — removes the silicone oil from the O-rings. Once dry, the O-rings lose their flexibility and the pump begins to lose vacuum during the pumping process, reducing effectiveness. Applying several drops of this light silicone oil to the O-rings after each cleaning restores their pliability and maintains the vacuum seal, prolonging the pump's effective service life.

Key Features

• Maintains O-ring pliability and vacuum seal integrity — the two O-rings in the outer slide tube are the primary vacuum-sealing components of the Vacurect pump; keeping them lubricated with silicone oil prevents drying, cracking, and loss of elasticity that leads to vacuum leakage during pumping
• Required after each soap-and-water cleaning — mild soap and water cleaning is necessary for hygiene and is recommended for Vacurect pumps; however, soap and water also remove the silicone oil from the O-rings; reapplying several drops after every cleaning session maintains the O-rings in optimal condition
• Compatible with all Bonro Vacurect models — formulated for use with all current and prior Vacurect pump models; also suitable for other brands of VED pumps that specify O-ring lubrication as part of their maintenance protocol
• Light silicone oil formulation — light viscosity flows easily into the O-ring seat and distributes evenly; does not leave heavy residue on pump surfaces
• Pump use only — not a personal lubricant — this product is a mechanical device lubricant; for personal lubrication during VED therapy, a water-soluble personal lubricant is the appropriate product; using mechanical silicone oil as personal lubricant is not appropriate and is not the intended use of this product

Clinical FAQs

How do I apply the silicone oil to my Vacurect pump and how often should I do it?

Apply the silicone oil each time after cleaning the pump with soap and water. To apply: disassemble the pump components per the instructions in your Vacurect user manual to access the outer slide tube and its O-rings. Apply several drops (typically 3 to 5 drops) of the silicone oil directly onto each of the two O-rings seated within the outer slide tube. Distribute the oil evenly around the O-ring circumference by rotating the slide tube or using a clean fingertip to spread the oil. Reassemble the pump components and operate the slide mechanism a few times to work the oil into the seal before use. The oil application is straightforward but requires correct identification of the O-ring location within the pump housing — if you have difficulty locating the O-rings or are unsure how to disassemble your specific Vacurect model, Bonro provides a maintenance demonstration video at their website and on YouTube. The frequency of oiling corresponds directly to the frequency of cleaning: any time you clean the pump with soap and water, the O-rings should be re-oiled immediately after drying. Users who clean their pump weekly should oil weekly; users cleaning more frequently should oil with equal frequency.

What happens if the O-rings dry out and how do I know if my pump needs lubrication?

The O-rings in a VED pump function as the primary vacuum-sealing components of the sliding mechanism. When the O-rings are properly lubricated, the outer tube slides smoothly and maintains consistent negative pressure within the cylinder throughout the pumping strokes. When the O-rings dry out, two problems develop. First, the O-ring material loses the flexibility it needs to maintain contact pressure with the tube wall as the tube slides — small gaps form intermittently and air enters the cylinder, reducing or eliminating the vacuum with each stroke. Second, dry O-ring material is more susceptible to cracking, tearing, or permanent deformation from the friction of repeated dry sliding — damage that is not reversible by subsequent oiling and requires O-ring replacement. The most common sign that the O-rings need lubrication is a noticeable loss of vacuum during pumping: the user pumps but the cylinder does not maintain negative pressure between strokes, or the vacuum that builds releases more quickly than it previously did. Stiffness or resistance in the sliding mechanism can also indicate dry O-rings. If the pump has not been used for an extended period, the O-rings may have dried even without recent cleaning — applying the silicone oil before resuming use is advisable after any period of non-use of several weeks or more.

What is a vacuum erection device (VED) and who uses one?

A vacuum erection device (VED), also called a vacuum pump or penile pump, is a non-pharmacological, non-surgical medical device used in the management of erectile dysfunction (ED). The device consists of a clear cylinder placed over the penis, a pump mechanism that creates negative pressure within the cylinder, and tension rings (also called constriction rings) that are placed at the base to maintain the erection after the vacuum is released. VEDs are clinically indicated as a first-line or supplementary treatment for erectile dysfunction in a range of patient populations. They are particularly valuable for patients who cannot use oral PDE5 inhibitors (sildenafil, tadalafil) due to contraindications such as concurrent nitrate medication use or cardiovascular risk factors; for men who prefer a non-pharmacological approach; and for post-prostatectomy patients recovering erectile function, for whom VED therapy is sometimes recommended as part of penile rehabilitation protocols to maintain tissue oxygenation and prevent fibrosis during the recovery period before natural erectile function returns. VEDs are also used by patients with diabetes-related vascular ED, neurogenic ED from spinal cord injury or multiple sclerosis, and other conditions where pharmacological options are insufficient or not preferred. The Vacurect is a specific brand of VED that uses a compact design with the tension ring pre-loaded on the device, streamlining the pumping and transfer process. Maintenance of the pump mechanism with the appropriate silicone oil is a necessary part of device care that directly affects therapy effectiveness.
