1. Quality and Tests

2. Purchasing, forming and manufacturing only the best material Latest production technology is the guarantee for highest quality on a constant level Quality checks go along with the manufacturing process Quality management acc. ISO 9001 Chromium6-free protective coating CF for highest corrosion resistance Nut waxing and silver plating treatment for easy and safe assembly (EO fittings only) Optimised surface friction for easy and safe assembly (T-Lok and O-Lok) Quality and Tests Product quality as prerequisite for a leak free system

3. How to identify Parker-Quality? Parker Products are marked with a Parker trademark 24° cone fittings standardised in ISO 8434-1 & 4 are branded with “EO“ (Ermeto Original) Parker Triple-Lok ®, O-Lok ® and BSP Adapters are marked with “P” (Parker) EO Stainless steel items are supplied with “EODUR“ nuts

4. Identification DIN EO-nuts Part No.: M15LCFX EO 15-L Tube OD EO Identification Series Tube size

5. Identification SAE-nuts TypeParker SignHex Identification Size T-Lok"P" "MM"e.g. 14-16 O-Lok"P""MM"e.g. 10BML The 14-16 on the T-Lok nut shows the metric range of tube sizes that can be used with the size of connection. P 10 BML Size / Type MM Parker Identification Metric Hexagon Example: O-Lok nut

6. Safety First Test procedures for fittings according to DIN 3859-3 / ISO 8434-5

7. Test procedures for fittings Assembly according to DIN 3859 - 2 Repeat assembly 6X60° removed Fatigue test 10million load cycles Leak test 100 bar Burst pressure PN X 4 (bar) Pressure impulse PN X 1,33

8. Assembly according DIN 3859-2 Cut tube squarely. Max +/- 1° deviation 1 2 Max. chamfer 0.3mm x 45°. Remove burrs 3 Lubricate thread and cone.Threads on stainless steel must be lubricated. Use EO-Niromont special high-efficient lubricant for stainless steel. This pre-assembly is for DIN Fittings only!

9. Assembly according DIN 3859-2 4 5 Check correct ring position and orientation Press tube end firmly into fitting body Screw on nut until finger-tight Mark position of the nut Tighten the nut by 1 1/2 turns 1 1/2

10. Assembly according DIN 3859-2 5 Loosen nut Check to make sure that a visible collar covers the front of the first cutting edge 6 For re-assembly the nut must have the original position Then tighten fitting firmly by 30° (1/2 flat)

11. Assembly and integrity test (Repeat assembly followed by gas leakage test under water) Three examples from the pre-assembly must be used Internal Pressure 100b

12. Static burst pressure test Medium: Hydraulic oil e.g. HLP 32 Pressure: 4 x PN Duration: 3 Minutes Criteria: During the test ; no oil loss 4 X PN 3 Minutes

13. Vibration test (Vibration test with a bending stress of 25% of the tube tensile yield stress in N/mm² and 10,000,000 cycles) P D pressure L Y Y =Amplitude S =Bending stress 25% of the tube L =Length E =Modulus of Elasticity D =Tube outside diameter

15. Test: concurrent- 1.5 x nominal pressure 500,000 cycles 25% Tube elastic limit 10 Million cycles Combined Vibration and Impulse test

16. Type P[bar] GE06SREDOMDCF800 Minimum burst pressure (static, 3 Minutes, 4 x PN) 3200 Minimum Impulse resistance: (dynamic, 1M cycles, 1.33x PN) 1064 Example DIN:

17. Example SAE: Type P[bar] 4-5 F5OX-S (straight fitting steel) 420 Minimum burst pressure (static, 3 Minutes, 4 x PN) 1680 Minimum Impulse resistance: (dynamic, 1M cycles, 1.33x PN) 559

18. Corrosion resistance test Chromium6-free surface of fittings 500 hrs to white rust with a salt spray test according to DIN 50021 / ISO 9227 for DIN-fittings Corrosion test with a 5% sodium chloride solution in a vapour bath with a temperature of 35°C Resistant to all hydraulic- and bio-degradable Oils like HLP,HETG, HEPG, HEES,..
