Impossible Seal -- Compatibility, or Misuse?

So, I bought a 9 inch long, 2.25 inch wide contoured cylinder from Boston Pump

And a deluxe brass pump from LA Pump

The connector fits in snugly and I always made sure my genital region was properly shaven (including my scrotum) and lubricated. However, each session, it became impossible to keep a consistent amount of pressure without occasionally squeezing the pump handle, especially if the skin to my scrotum and crotch weren’t sucked in enough. I figured the mistake I made was the fact that I have a 1.5 inch wide penis whereas forums suggest only going up to half an inch above that for cylinder circumference.

So I decided to buy a 9 inch long, 1.75 inch wide flat-end cylinder, again from Boston Pump

This time, my penis felt a lot more snug in there and the pressure felt more.. Efficient. The problem, though, is that the seal was even worse with this cylinder. The pressure would escape almost immediately to where I’d have to rapidly pump just to keep the pressure equal, regardless of how hard I’d press the base of the cylinder against myself. Yet I couldn’t quite feel the air escaping at any particular point of the setup.

The thing is, if you notice with the connectors for the cylinders at LA Pump, they appear to be the same as that of Boston Pump. But perhaps I’m wrong. Does anyone know of the compatibility between the two products?

It would be less favorable to have to buy a third cylinder elsewhere.

I use lube on my member to make sure it doesn’t stick to the sides. When I put the tube on, I press firmly and twist to the left and right to ensure I’ve made a good seal. I connect the pump and have no issues. Make sure all of the hair is trimmed nice and short since that can be a problem.

Make sure you tightened the connector by screwing it in firmly. Its my number one reason for leaks

What is your actual, circumference? At the area behind the glans, the mid shaft, then the base? The most common issues for leakage is not fitting a tube properly to your size or shape. Measurement would help me guess what your issue could be.

Just FYI, the $70 ‘deluxe brass pump’ from LA Pumps is a $25 brake bleeder from Harbour Freight with a sticker on it Brake Bleeder and Vacuum Pump Kit

I had the same issue. For me it was the connector on the cylinder itself. Tighten it down some just don’t go too tight or you may crack the fitting or even the cylinder itself.
