Quality and Tests

Quality and Tests Product quality as prerequisite for a leak free system • 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 • Chromium 6 -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)

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

Identification DIN EO-nuts Part No. : M 15 LCFX Tube OD EO EO Identification Tube OD 15 -L Tube size Series

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

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

Test procedures for fittings Assembly according to DIN 3859 - 2 Repeat assembly 6 X 60° removed Leak test 100 bar Burst pressure PN X 4 (bar) Fatigue test 10 million load cycles Pressure impulse PN X 1, 33

Assembly according DIN 3859 -2 This pre-assembly is for DIN Fittings only! 1 2 • Cut tube squarely. • Max +/- 1° deviation • Max. chamfer 0. 3 mm 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.

Assembly according DIN 3859 -2 1 1/2 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

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

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

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

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

Combined Vibration and Impulse test Test: concurrent 1. 5 x nominal pressure 500, 000 cycles 25% Tube elastic limit 10 Million cycles

Example DIN: Type GE 06 SREDOMDCF Minimum burst pressure (static, 3 Minutes, 4 x PN) Minimum Impulse resistance: (dynamic, 1 M cycles, 1. 33 x PN) P[bar] 800 3200 1064

Example SAE: Type 4 -5 F 5 OX-S (straight fitting steel) Minimum burst pressure (static, 3 Minutes, 4 x PN) Minimum Impulse resistance: (dynamic, 1 M cycles, 1. 33 x PN) P[bar] 420 1680 559

Corrosion resistance test Chromium 6 -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, . .
