82834 - High-Side Manual R134a Coupler (14 mm-F x 16 mm)
Mastercool’s R134a Manual Coupler Kit starts with a single forged brass body — no welded seam, no joint, no weak point. Every dimension, from the seal gland to the hex, is engineered to spec rather than left to chance, giving technicians a coupler that adjusts easily to varying service port dimensions, seals right, and protects the valve core on every connection.
FEATURES:
- One-Piece Forged Brass Body: No welded seam like a two-piece machined body — just solid, forged brass holding its shape and seal integrity through years of daily use
- No Loss Disconnect: Removes the coupler at any knob position without losing refrigerant, thanks to a patented internal sealing mechanism
- Patented Spring-Loaded Depressor: Manufactured to reach the maximum valve core depth specified by SAE guidelines, ensuring reliable, consistent engagement across standard service ports
- Precision-Machined 18mm Hex: Machined to a true 18mm after forging, so a standard wrench seats perfectly every time — no rounded corners, no slipping
- Nickel-Plated Brass: Protects the body from corrosion and discoloration through years of shop use
- All-Metal Construction: No plastic components, built to hold up to drops, impacts, and daily wear
- Meets SAE, UL and EPA Requirements: For containment of refrigerant
