The MTM SGS28 Trigger is my own gun of choice for now. Slightly smaller in the hand than the SG35 and SGS35 variants, this gun utilizes plated and stainless for better corrosion re sistance than brass units. Swiveled base helps eliminate hose-wrap and helps with wrist fatigue on a long job. This may be the 'compromise', middle of the road option offered by MTM, but the value and weight savings the SGS28 offers makes it my pick. Rebuild kits are also available for these triggers should something go wrong. Understanding Temp Ratings: Each MTM Trigger has a temperature and pressure rating. This rating refers to the capacity of the internal piping and brazing to withstand temps, not necessarily the fittings and o-rings associated with each build. Standard fittings (used in each build here) utilize a nitrile o-ring which has a melting point of around 250ºF. This figure may vary depending on the changes in nitrile blend than can occur in production. If you are using this gun or any other with a heated system, it is advised that a PTFE or Viton o-ring is sourced to handle associated temperatures the gun will experience. This option has a 450ºF melting point and is better suited for your application. The rating stated on the side of each trigger is for the trigger internals, and not for the associated components. Made from industry leading materials by MTMHYDRO in ITALY. Optional PRIMA fittings may be selected with your purchase Show more
