Pump Sleeve Advanced Silicone Blue for Cylinders up to 7.5 cm

Pump Sleeve Advanced Silicone Blue for Cylinders up to 7.5 cm 🖤

The Advanced Silicone Pump Sleeve by CalExotics from the Optimum Series is an accessory and not a pump: a soft blue sealing sleeve in silicone for the open rim of a matching pump cylinder. It is slightly translucent, smooth and cylindrical on the outside, and on the inside it slopes down in two soft steps to the round opening through which the penis enters the cylinder. Why it is needed becomes clear on the first attempt without one: the hard rim of a cylinder does not seal on skin, and without a seal no vacuum builds. The silicone sleeve conforms, turns the edge into a soft surface and also protects the skin from the hard rim. A pump that cannot be released immediately should not be used, so the sleeve only belongs on a cylinder with a release valve. Clean the sleeve separately from the cylinder with warm water, and it has to be completely dry before it goes back on. It sits under pumps, under sex toys for men and in our penile enlargement section.

❓ FAQ

Which pump does the sleeve fit?

Round pump cylinders up to the diameter given above. It is pulled over the open rim and holds by its own tension. If it sits loosely, the cylinder is too narrow and the seal will not hold.

How long may you pump?

Ten to fifteen minutes at a time, with the vacuum built slowly and with breaks. Pumping longer or harder risks burst capillaries and bruising.

What if it hurts?

Release immediately, even if it only pulls or burns. With a pump, pain is not a sign of effect but the signal that the pressure is too high.

Do you need lubricant?

Yes: a drop on the rim of the sleeve so it seals, and a little on the penis. Water-based is the right choice, the selection is under water-based lubricant.
