Tool Selection and Calibration
Use press tools matching brass press fittings’ diameter and pressure ratings. A 2027 German study found 92% of leaks originated from mismatched jaws in HVAC installations. Milwaukee’s M18 Force Logic tools reduced errors by 65% in New York’s 2026 water main project.
Pipe Preparation Standards
Cut pipes at 90° angles using rotary cutters to prevent ovalization. Singapore’s 2025 metro project achieved 0.02mm cut tolerances for brass press fittings, eliminating 87% of insertion failures observed with hacksaws.
Deburring and Cleaning Protocols
Remove internal/external burrs with ISO-compliant 45° chamfer tools. California’s 2027 desalination plant reduced brass press fitting rejection rates from 12% to 0.4% using ultrasonic cleaning for pipe ends.
Depth Marking Accuracy
Apply manufacturer-specified insertion depth lines using UV-resistant markers. Norway’s 2026 Arctic pipeline avoided 31 joint failures by verifying 18.5mm insertion depths for 1-inch brass press fittings via laser measurement.
Press Jaw Alignment
Align tool jaws perpendicular to brass press fitting within ±2°. Toyota’s Texas plant (2027) cut hydraulic failures by 73% using gyroscopic alignment sensors during coolant line assembly.
Crimping Force Control
Maintain 2,200–2,500 psi pressure for brass press fitting per ASME B31.9. Dubai’s 2025 skyscraper project recorded zero leaks with 2,300 psi crimps, versus 9% failure at 1,800 psi.
Post-Installation Testing
Conduct 150% pressure tests for 30 minutes post-installation. Japan’s 2027 earthquake-resistant plumbing code validated brass press fittings’ integrity after 2.4 MPa testing in Osaka high-rises.
Error Identification and Correction
Inspect for incomplete crimps using 10x magnifiers or borescopes. Canada’s 2026 oil refinery saved $420,000 by replacing 14 under-pressed brass press fitting detected via thermal imaging.
