Easy Installation & Stable Flow Transition for Flow Meter Reducer Fitting
Wide Compatible Application Scenarios
This quick-connect flow meter reducer fitting is designed for sanitation vehicle fuel pipelines, industrial fluid transportation and commercial metering systems. Made of lightweight aluminum alloy, it stably conveys water, diesel, gasoline and weakly corrosive chemical liquids within standard temperature range. Equipped with spring buckle quick coupling, it supports fast disassembly and connection for frequent pipeline maintenance, perfectly matching oval gear flow meters to realize smooth diameter transition and accurate flow measurement.
Wide Compatible Applicable Media & Diversified Working Scenarios
This aluminum quick-disconnect flow meter reducer fitting is generally mounted on hose terminals and hard pipe ports to realize diameter conversion between pipelines and oval gear flow meters. It fits multiple industrial fluid projects: oil tanker petroleum loading & unloading, non-dangerous liquid filling and transfer, ship refueling and ballast water circulation, cargo barge pipeline systems. It also works perfectly for coolant, lubricating oil, hydraulic oil, edible oil and other food-safe liquids, with reliable tight sealing to avoid leakage during long-term fluid transmission.

Body & Reducing Structure
This flow meter reducer fitting adopts smooth reducing transition cavity with uniform inner wall polishing. The gradual diameter change effectively lowers fluid resistance, eliminates turbulent flow interference, and guarantees precise flow data collection for matched oval gear flow meters without measurement deviation.
2
Quick Camlock Connection Structure
Equipped with standard aluminum camlock quick couplings with brass spring lock handles, the fitting enables tool-free rapid plugging and separation. The built-in thickened rubber sealing ring fits tightly between interfaces to prevent liquid seepage during long-time continuous fluid delivery.
3
Cast Material & Installation Structure
The reducer body is integrally cast from lightweight high-strength aluminum alloy, featuring anti-rust and impact-resistant performance. Flange connection plates with reserved bolt holes support easy fixed mounting on flow meter ports, and customized size, caliber and surface treatment are available upon buyers’ requests.

Outstanding Performance Edges Of Meter Reducer Fitting
Multi Superiorities: Quick Installation, Tight Matching & Stable Flow Conversion
Plug-and-play design eliminates tools like wrenches and screwdrivers. Align the male spigot with the female coupling and push into place, then fasten via the dual brass cam lock handles. To disconnect, just pull the brass latches outward for instant pipeline separation without extra steps.
Multi-layer sealing structure with built-in O-rings and end face gaskets. It forms tight static sealing after camlock locking, effectively blocking liquid and gas leakage during long-distance fluid delivery.
Heavy-duty self-locking mechanical structure stays firmly fastened. It will not loosen or detach accidentally under high pressure, large flow volume and frequent pipeline vibration.
Spray-proof automatic shutoff stops medium splashing during disconnection to protect operators and avoid site pollution. Labor-saving brass latches need designated pulling force to unlock, effectively avoiding accidental pipeline separation caused by unintended collision.
