BARBED FITTING TECHNICAL TCE
🧩 Materials & Construction
Materials:
Polypropylene (PP) – black or natural, UV-resistant, food-grade possible
Nylon (white/black) or Polyethylene (PE) in some lines
Barb Design: Multiple barbs—typically triple or quadruple—for secure hose retention when used with clamp
2. 🌡️ Temperature & Pressure Ratings
| Material | Temperature Range | Max Pressure |
|---|---|---|
| Polypropylene | –40 to +100 °C (–40 to 200 °F) | ~125 psi (8–9 bar) |
| Nylon / PE | –45 to +82 °C (–50 to 180 °F) | up to ~125 psi (8.6 bar) |
| Chemical-Resistant PP | –9 to +121 °C (15 to 250 °F) | 120 psi (~8.3 bar) |
| Reducing Tee (PP) | — | 4 bar (~58 psi) |
3. 📏 Sizes & Configurations
Tee (Barb to Barb):
Full sizes: 3/16″–1″ ID (≈ 4–25 mm); reducing sizes like 3/8″→1/4″, 1/2″→3/8″ 90° Elbow:
Full sizes (PP/nylon/PE): 1/4″–1½″; reducing elbows e.g., 1/2″→1/4″, 1/2″→3/8″
V‑Shape / Y‑Splitter:
Male threaded base (in your image) – typical PP with ¾″ male NPT BSP base, two angled barbs (∼G½″ × 2 × 3/8″)
Barbed Adapters:
Male: Barb × male thread (10-32 UNF / ¼″ NPT etc.) – e.g., Ø1.6 mm–4.3 mm ID tube, threads seal without gasket
Female: Barb × female cap – similar design but with internal thread
Couplers / Unions:
Straight barb-to-barb couplers for extending hose length
End Caps:
Simple barb end closures for sealing unused hose lengths
4. 🛠️ Installation & Performance
Hose ID compatibility: Yes – barbs are sized for proper tube IDs (e.g., B80: 1.6 mm; B85: 3.2 mm; B86: 4.3 mm)
Secure connections: Use hose clamps for >50 psi; single barb plus rib for 75+ psi in nylon
Threaded ends: Male/female adapters may be sealed with PTFE tape, thread itself often gasketless in precision-molded PP
5. ✅ Applications
Low- to medium-pressure fluid systems (water, chemicals, air)
Agriculture, irrigation, beverage/food grade (with FDA-compliant materials)
Pneumatic, laboratory, or cooling circuits
Chemical-resistant applications using specific PP or PVDF variants

📘 Notes & Recommendations
Always match hose ID to barb size.
Use hose clamps above ~50 psi.
For threaded adapters, a PTFE sealant or tape may be needed.
Support UV & chemical exposures by choosing black PP or PVDF variants
