9. FAQ: Professional rubber air hose 3 8 Knowledge Base

Frequently Asked Questions

Q1: What material is used for your rubber air hose 3 8, and why?
A: Our hoses use premium NBR (nitrile butadiene rubber) or CR (chloroprene rubber) for the tube and cover, providing superior oil resistance, temperature tolerance, and aging stability. The reinforcement utilizes high-tensile steel wire braid for strength and flexibility.
Q2: Which standards apply to rubber air hose 3 8 production and testing?
A: We comply with DIN EN853 1SN, SAE 100 R1 AT, ISO 9001:2015 certifications, with in-house test methods following SAE J343 for pressure impulse, burst tests, and ISO 14001 for environmental management.
Q3: Are all rubber air brake hose fittings compatible with your hose?
A: All hoses are manufactured with standardized outer diameters and wall thickness for seamless crimping/swaging with air brake, quick-connect, or screw-type fittings as per SAE J1402 or equivalent.
Q4: How do you guarantee heat resistance and anti-aging?
A: The compound features UV stabilizers, carbon black, and synthetic polymers. Each batch undergoes 168h accelerated aging and 120°C thermal cycling, meeting or exceeding OEM specifications for heat resistant rubber hose.
Q5: What factors determine the minimum bend radius for installation?
A: Bend radius is affected by ID/OD, reinforcement structure, and cover material. For 3/8" ID versions, our minimum static bend radius is 95mm, ensuring no kinking or performance loss in tight routing.
Q6: Can I order hoses in non-standard sizes, e.g., 3/4 id rubber hose or shorter/longer lengths?
A: Yes, we offer full customization. Inner diameters from 1/4" to 2”+, with continuous lengths up to 100 meters, or pre-cut to customer specs. Covers: wrapped, smooth, or color-coded per requirement.
Q7: What is your defect rate and how is it managed?
A: Our outgoing defect rate is <0.08%. We implement full lot traceability, 100% pressure and conductivity testing, and root-cause defect analysis using SPC methods as per ISO 2859-1.
