    Thank you for the response. The only thing I purchase is HDPE. And yes, canisters such as Geisha, American Glory, and other canisters that are 6" in height. I can easily purchase 15" tubes but hard to find 18" tubes.

    Thanks, I did purchase mortar tubes from a company and the wall thickness is thinner, having a true inside diameter of 4". I plan to test it out soon, if its a tight fix, then its a no go for launch. I'll report back on my findings.

    Since you say it is 3.9 ID is probably DR 15.5 or DR17.
    I want to to say the companies I shoot with use DR 13.5 or DR11 so ID of 3.79-3.63 respectively. Once in great while we get an odd shaped shell or one with extra tape/paper that makes a tight fit. So yes you should be golden with that pipe.

    Dimension Ratio, DR, is the ratio of the pipe outside diameter to the pipe minimum wall thickness. As diameters change, the pressure rating remains the same for the same material, dimension ratio and application.
