Mastercool 82934-E Low-Side Manual Coupler, 1/4" Male Flare x 13mm, Blue

• The Mastercool 82934-E is a low-side manual R134a coupler connecting a 1/4" male flare fitting to a 13mm service port. It features a one-piece forged brass body with a precision-machined 18mm hex and a nickel-plated finish, and is color-coded blue for low-side identification.
• Features:
  • One-piece forged brass body with no welded seam, holding its shape and seal integrity through years of daily use.
  • No-loss disconnect removes the coupler at any knob position without losing refrigerant, using a patented internal sealing mechanism.
  • Patented spring-loaded depressor reaches the maximum valve core depth specified by SAE guidelines for reliable, consistent engagement.
  • Precision-machined 18mm hex, machined to true size after forging, so a standard wrench seats perfectly every time.
  • Nickel-plated brass protects the body from corrosion and discoloration through years of shop use.
  • All-metal construction, with no plastic components, built to hold up to drops, impacts, and daily wear.
  • Meets SAE, UL, and EPA requirements for refrigerant containment.
  • Blue color coding identifies this as a low-side coupler.
