Part Number & Identification Guide

1️⃣ Why Part Number Identification Is Critical

In hydraulic systems, a part number is not just a product code.
It is a complete technical description that defines:

• How the fitting connects

• What hose it fits

• What pressure it can handle

• How it seals

Even a small mistake (wrong pitch, wrong angle, wrong dash size) can cause:

• Oil leakage

• Hose blow-off

• Equipment damage

• Serious safety accidents

2️⃣ Core Principle (Golden Rule)

Never write a part number before full identification is complete.

You must first identify:

1. Hose size

2. Fitting shape

3. Thread standard

4. Thread size

5. Thread pitch

6. Sealing method

7. Hose dash size

If one item is missing → STOP.

3️⃣ Standard Structure of Hydraulic Fitting Part Numbers

Most global manufacturers follow this logic:

[Series Code] – [Thread Size × Pitch] – [Hose Dash Size]

Each part of the code has a technical meaning.

4️⃣ Understanding the Series Code (MOST IMPORTANT)

The series code tells you:

• Fitting type

• Angle

• Sealing method

Example (Common Market Series)

👉 If series code is wrong, the whole part number is wrong.

5️⃣ Writing the Technical Specification (Before Part Number)

Always write the technical specification first.

Example Specification

6 × M14 × 1.5 C 90°

Meaning

• 6 → Hose inner diameter (mm)

• M14 → Metric thread, 14 mm

• 1.5 → Thread pitch (distance between threads)

• C → Cone seal

• 90° → Elbow angle

This specification is independent of brand.

6️⃣ Converting Specification → Vendor Part Number

Step-by-Step Example

Specification:

6 × M14 × 1.5 C 90°

Identify series:

• Metric cone

• 90° elbow
  → Series = 30792

Add thread & hose size:

30792-14×1.5-04

✔ This is the correct vendor-facing part number

7️⃣ Hose Dash Size Mapping (Myanmar Market Critical)

⚠️ Hose size ≠ Thread size (Never confuse these).

8️⃣ Internal Code vs Vendor Code (IMPORTANT RULE)

Vendor / External Communication

30792-14×1.5-04

✔ Pitch MUST be included

Internal / Store Short Code

30792-14-04

⚠️ Only allowed if pitch is already confirmed and documented

9️⃣ Full Customer Sample Identification SOP

Step 1 – Clean the Sample

Remove oil, dirt, old tape, sealant.

Step 2 – Identify Shape

• Straight / 45° / 90°

• Myanmar: တည့် / ၄၅ အကွေး / ၉၀ အကွေး

Step 3 – Identify Male / Female

• Threads outside → Male

• Threads inside → Female

Step 4 – Measure Thread Diameter

• Use caliper

• Record OD (male) or ID (female)

Step 5 – Measure Thread Pitch

• Use pitch gauge

• Match exactly (no gap)

Step 6 – Identify Seal Type

• Cone

• O-ring

• Flat face

• Taper thread

Step 7 – Identify Hose Size

• Measure hose ID

• Confirm dash size

Step 8 – Write Specification

Hose × Thread × Pitch + Seal + Angle

Step 9 – Convert to Part Number

Use series code + measured values.

🔟 Real Myanmar Market Examples

1️⃣1️⃣ Common and Dangerous Mistakes

• Writing part number without pitch

• Guessing by visual similarity

• Mixing BSP and Metric

• Using old fitting as reference without measuring

• Reusing damaged fittings

Part Number & Identification Guide (အသေးစိတ် – လက်တွေ့အသုံးချ)

၁️⃣ Part Number ကို ဘာကြောင့် မှန်မှန်ရေးရသလဲ

Part Number ဆိုတာ
ပစ္စည်းအမှတ်မဟုတ်ပါ။
နည်းပညာအချက်အလက် အပြည့်အစုံ ဖြစ်ပါသည်။

တစ်ချက်မှားရင်—

• ဆီယိုမယ်

• တပ်မရ

• Hose ပြတ်မယ်

• အန္တရာယ်ဖြစ်နိုင်

၂️⃣ အခြေခံစည်းမျဉ်း (အရေးကြီးဆုံး)

မတိုင်းမချင်း Part Number မရေးရ

အောက်ပါအချက်အားလုံးကို မဖြစ်မနေ သိရပါမည်–

1. Hose size

2. Fitting ပုံသဏ္ဍာန်

3. Thread standard

4. Thread အချင်း

5. Pitch (အရစ်အကွာ)

6. Seal နည်း

7. Hose dash size

၃️⃣ Part Number ဖွဲ့စည်းပုံ

[Series Code] – [Thread Size × Pitch] – [Hose Dash]

၄️⃣ Series Code ကို နားလည်ခြင်း

Series Code က—

• တည့်လား

• အကွေးလား

• Cone လား / Flat လား

ကို ပြောပြပါတယ်။

၅️⃣ Specification ကို အရင်ရေးပါ

6 × M14 × 1.5 C 90°

ဆိုတာကို အရင်ရေးပါ။
ပြီးမှ Part Number ပြောင်းပါ။

၆️⃣ Part Number ပြောင်းနည်း

30792-14×1.5-04

✔ Vendor ကို ပို့ရမည့် အမှန်ဆုံး Format

၇️⃣ မြန်မာဈေးကွက် အရေးကြီးအချက်

• “ခွက်” = Hose size

• M14 / M30 = Thread size

• နှစ်ခု မတူပါ ❌

၈️⃣ Customer Sample စစ်နည်း (အကျဉ်း SOP)

1. သန့်ရှင်း

2. တည့် / အကွေး

3. Male / Female

4. အချင်းတိုင်း

5. Pitch တိုင်း

6. Seal စစ်

7. Hose size စစ်

8. Spec ရေး

9. Part Number ပြောင်း

၉️⃣ မဖြစ်သင့်သော အမှားများ

• Pitch မရေး

• မြင်ရတာနဲ့ ခန့်မှန်း

• Standard ရော

• ပစ္စည်းဟောင်းကို Reference လုပ်

🔟 သတိပြုရန်
