GENTLE BF□U / BF□-01 Nut-Clamp Fittings｜M5 / RC1/8 · For PU / Nylon Tu

• Secure Threaded Connection: Two male-thread options—M5×0.8 (BF☐U) and RC1/8 (BF☐-01, BSPT)—for positive seating and vibration resistance.
• PU & Nylon Compatibility: Fits PU 4×2.5 / 6×4 and nylon (PA) 4×2.5 / 6×4 with firm grip for frequent service.
• Airtight & Durable: Rubber washer (face seal) + clamp mechanism with nickel-plated brass body ensures long-term sealing and reusability.
• Installation-Friendly: Supplied with a rubber washer; for RC threads, apply a thin thread sealant or PTFE tape per site practice (keep it out of the flow path).
• Made in Taiwan: Tight dimensional control supports standardized spares and long-term maintenance.
• Applications: Cylinder/fixture straight runs, high-frequency test ports, short hose links on robot EOAT, retrofits from legacy lines to PU/nylon, tight wall-side straight routing, centralized take-offs on valve islands.

Q1: What's the difference between BF☐U and BF☐-01?
A: BF☐U uses M5×0.8; BF☐-01 uses RC1/8 (BSPT). Choose by your port spec.

Q2: Which tube materials and sizes are supported?
A: PU and nylon (PA) in 4×2.5 and 6×4. For non-standard tolerances, perform on-site pull/leak tests.

Q3: Do I need thread sealant or PTFE tape?
A: The M5 side typically seals with the rubber washer; for RC1/8, use a thin sealant or PTFE tape per site practice, keeping sealant out of the flow path.

Q4: Is it reusable?
A: Yes—inspect the rubber washer, grip teeth, and threads at each service; replace worn consumables.

Q5: How to fix minor leakage?
A: Ensure a square, burr-free cut, full insertion, and proper tightening. Treat RC threads as specified. If leakage remains, check the rubber washer, thread integrity, and tube OD.

Q6: Vacuum or higher pressure use?
A: Intended for clean, dry compressed air. For vacuum, higher pressure, or special media, verify material compatibility and proof-test first.
