Product Overview
Brass compression fittings provide a reliable mechanical connection method for various piping systems. These fittings utilize a compression mechanism to create secure, leak-proof joints without requiring soldering or specialized tools. The dezincification-resistant brass construction ensures long-term durability in demanding applications.

Installation Procedures
Pre-Installation Requirements
- Pipe preparation:
- Square cut using appropriate tubing cutter
- Complete deburring of cut ends
- Surface cleaning to remove contaminants
- Component verification:
- Confirm fitting size matches pipe OD
- Inspect compression components for damage
- Verify proper orientation of sealing elements
Assembly Process
- Slide compression nut onto pipe

- Test at 1.5x working pressure
- Minimum test duration: 15 minutes
- Leak detection method: Soap solution application
Maintenance Protocol
Preventive Maintenance
- Annual inspection schedule:
- Visual examination for corrosion
- Tightness verification
- Seal condition assessment
- Five-year comprehensive evaluation:
- Internal inspection where possible
- Pressure testing
- Component replacement as needed
Troubleshooting Matrix
| Symptom | Probable Cause | Corrective Action | Verification Method |
|---|---|---|---|
| Minor leakage | Insufficient compression | Re-tighten to specification | Pressure test |
| Persistent leak | Damaged compression ring | Replace ring component | Visual inspection |
| Difficult disassembly | Thread corrosion | Apply penetrating lubricant | Functional test |
| Fitting deformation | Over-tightening | Complete replacement | Dimensional check |
