Safety and Reliability
Minimal product leakage during disconnect increases site safety.
Low risk of leakage because of a proven seal design.
Four, "true interlocking" stainless steel latches ensure superior latch alignment and maximum safety.
Lightweight without reducing safety and reliability.
High-quality components including a stainless-steel collar and hard anodized aluminum body for increased service durability and life.
Performance and Convenience
Fast and easy disassembly of entire coupler through U-pin design.
U-pin is secured when the TTMA flange is fastened to prevent the pin from falling out in service.
Fast in-field replacement of main seals, on or off the arm.
Two operating handle sizes to suit customer preference.
Less drippage at disconnect compared to previous models.
Collar designed to ensure minimal distortion of critical latching face.
Easy to operate handle with a noticeable positive lock.
Comfort and Style
Ergonomic operating handle and carry loop results in less physical strain on users.
Handle Length
Short (150mm) or Long (200mm).
