Description
Overview:
The Coupling QR Female HQ12 - 12SAE is a non-genuine, heavy‐duty hydraulic quick release female coupling for JCB machinery. It replaces OEM reference 45/920047 and is commonly used on JCB 4CX and 3CX models. Built from robust machined steel with a corrosion‐resistant finish, it is designed for fast, secure connection and disconnection of hydraulic lines during daily use and servicing. The SAE -12 size interface suits a wide range of JCB hydraulic circuits, helping to minimise fluid loss and reduce downtime when changing attachments or carrying out maintenance. Its compact, straight‐through design supports reliable flow, while the precision fit and sealing surfaces aim to deliver a tight, leak‐resistant connection in demanding site conditions.
Key Features:
- Non-genuine replacement for OEM 45/920047 for cost‐effective maintenance
- Female quick release coupling in SAE -12 size for common JCB hydraulic systems
- Strong steel body with corrosion‐resistant finish for long service life
- Smooth sleeve action for quick, tool‐free connect and disconnect
- Designed to maintain a secure, leak‐resistant seal when correctly fitted
- Precision‐engineered to meet typical industry performance expectations
- Suitable for frequent coupling cycles in harsh environments
- Straightforward installation; compatible with standard hydraulic hoses and ports specified for this size
Typical Applications:
Used to connect and disconnect auxiliary hydraulic circuits on excavators, loaders, and telehandlers. Common for attachment changes (e.g. breakers, augers, grabs), workshop servicing, and hose replacements. Well suited to plant hire, construction, utilities, agriculture, and groundworks where reliable, fast hydraulic connections reduce downtime.
Also known as:
Quick release female coupling, QR female coupler, hydraulic quick connector, hydraulic hose coupling, hydraulic coupler female half, SAE -12 female coupler, hydraulic disconnect fitting.
