Hey Ronnie,
Thanks for taking the time to leave us a review on this product. We are sorry to hear that you're not having a great experience with that carb cap, but just wanted to note that it is meant to be used with our XL Quartz Bangers (https://www.420science.com/products/4mm-xl-quartz-banger-14mm). It may function with other similar bangers, but it works best with those XL Quartz Bangers we sell.
