These are Enderle screw-in bypass pills (7/16"-20 thread). We carry these in INCREMENTS OF .005" ONLY from .035" all the way up to .200". If you order the "Flowed" option from the pull-down above, then the pills will have been flow tested and matched to within +/-1% of what they are supposed to flow according to our chart. You'll receive a report of what each bypass pill you order flows @100 PSI @.792 SG. If you need numbers at a different pressure or specific gravity, please specify in the comments section of your order. Specify decimal diameter SIZES in the comments section of your order.
