134-512-134 is a "larger tip" meaning it's orifice & it's fan pattern at 10" from what you are spraying is larger than the standard 134-509-114 tip that Sames puts in the box with their Xcite+ spray gun. When Jeremy says "High Production" he is referring to the fact that due to a larger orifice size, more material will come out of the 12-134 tip, as compared to the 09-114 or 09-094 tips. To break down the part number of Sames spray tips; All tips for the Xcite gun follow this format, "134-5XX-XXX". The first two X's are referencing the orifice size of the tip. The higher the number, the larger the orifice. The next three X's are referencing the width of the fan pattern at 10" from your product. The higher the number, the wider the fan pattern. www.grapekaction.com/images/uploads/Kremlin%20Tip%20chart-%20Grapek.pdf
Thanks for the question! If you'd like, shoot us an email at info@grapekbates.com and we can ask some follow up questions regarding your material and equipment to make a recommendation for you!
We would recommend an 09-092 that is what we see standard. If your latex is super thick and you still are not getting enough material we would want to move you up to an 12-092.
