Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- Chinese mini excavators with matching M14 and M18 DIN hydraulic connections
- Compact equipment and attachments using the same thread pitch and sealing seat
Product Overview
A replacement thumb, breaker, grapple, or hose can arrive with the right pressure rating but the wrong metric end. These adapters are meant to bridge the listed M14 and M18 connections without cutting into a usable hose assembly.
Metric thread diameter does not identify the sealing system by itself. DIN compression, metric straight thread, cone seats, and bonded-seal ports can look similar but will leak or damage threads if mixed. Measure pitch, identify male and female sides, compare sealing faces, and confirm the circuit pressure before installation.
Key Features & Performance
- Adapts between listed M14 and M18 hydraulic connections
- Useful for compact excavator attachment and service plumbing
- Avoids replacing an otherwise serviceable matching hose
- Metric fitting format for compatible imported equipment
Common Uses
- Connecting an attachment hose with a different metric end size
- Correcting a fitting mismatch during hydraulic repair
- Keeping common compact-excavator adapters in a service kit
Technical Specifications
- Product Type: Metric hydraulic fitting adapter set
- Connection Sizes: M14 and M18

Installation & Fitment

Frequently Asked Questions
Q: Does M14 to M18 guarantee the adapter will seal? A: No. Thread pitch, seat angle, male/female orientation, and sealing method must also match.
Q: Can thread tape be used? A: Only if the equipment specification calls for it; many hydraulic fittings seal at a cone, flare, or bonded washer instead.
Q: Will this fit every Chinese mini excavator? A: No. Imported machines use several fitting standards and hose layouts.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
