MTM SG35 Pressure Washer Trigger Solid, durable brass construction that will last for years. If built option is selected, these are hand assembled by yours truly, QC fittings wrapped and torqued. Slightly heavier than the stainless unit, but every bit as functional and retains an integrated swivel. By no means a budget or cheap unit, manufactured with industry leading materials in ITALY by MTM Hydro. 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.
