IFAN Unique Design Brass Press Fittings

Visual inspection after crimping
After crimping, inspect the Brass Press Fittings visually. There should be clear marks from the jaws. The crimp should be even with no skew. Example: tool marks visible around the entire circumference.

Checking crimp depth
The crimp should be uniform across the length. Jaws must close fully with no gaps. No slits or openings are acceptable. Brass Press Fittings require a complete, full-depth crimp.

No visible damage
The fitting must show no cracks or scratches. Surface should be clean and smooth. Brass Press Fittings without damage indicate proper installation.

Verifying pipe insertion
The pipe must be inserted to the full depth. You should see the insertion depth mark on the pipe. Brass Press Fittings with full insertion are reliable.

O-ring position check
The seal must not be extruded outside the fitting. It should be uniformly compressed. Brass Press Fittings with proper O-ring compression seal correctly.

Hydrostatic pressure testing
The most reliable method is system pressure testing. Raise pressure to 1.5 times working pressure. Hold for 15-30 minutes. Brass Press Fittings are verified under test pressure.

Example: heating system pressure test
The system is filled with water under pressure. Pressure is held for 30 minutes. Brass Press Fittings show no leaks. Example: successful pressure test confirms sealing.

Example: gas system leak test
Soap solution is applied to all joints. Bubbles indicate a leak. Brass Press Fittings with no bubbles are sealed. Example: a simple but effective test for gas.

Using electronic leak detectors
Electronic sensors can find even small leaks. They detect gas and air leaks. Brass Press Fittings are checked with instruments.

Checking fitting marking
The marking should be clear and legible. It indicates type and size. Brass Press Fittings with correct markings.

Checking crimping force quality
If a calibrated tool was used, the force is correct. Good crimps show uniform marks. Brass Press Fittings with correct force are reliable.

Final signs of a correct crimp
Brass Press Fittings are correctly crimped if: tool marks are visible, no damage is present, pipe is fully inserted, O-ring is uniformly compressed. Pressure testing confirms sealing. Soap solution shows any leaks. Leak detectors find micro-leaks. Brass Press Fittings meeting these criteria are sealed. Example: follow these steps to ensure proper installation.
