Our dedicated air compressor diaphragm fits intake valves, pressure switches, capacity control valves and other core parts, integrally molded with imported NBR / FKM rubber to solve air leakage, cracking, poor temperature and oil resistance:

1. Wide temperature range & anti-aging FKM version: -30℃~220℃; NBR version: -20℃~130℃. Stable under compressor high-temperature working conditions, no hardening or cracking. Service life 200% longer than recycled rubber diaphragms.
2. High elasticity & anti-fatigue for long cycle use Anti-fatigue additives mixed in raw materials, maintains shape after one million reciprocating stretches. Up to 1,000,000 working cycles, ideal for 24-hour continuous running compressors, cutting replacement frequency greatly.
3. Oil & corrosion resistant, leak-proof sealing Resist compressor oil, water vapor and weak acid/alkali, no swelling after long-time oil contact. Integral molding without splicing gaps, sealing leakage rate ＜0.1%, stably maintain standard working pressure and reduce wasted power.
4. Standard OEM size, direct replacement Manufactured with original factory molds, perfectly compatible with Atlas Copco, Sullair, Ingersoll Rand screw & piston compressors for intake valves and pressure switches. No cutting or modification required, complete replacement within 5 mins, custom special sizes available.
5. High tear resistance & toughness Tensile strength ≥18MPa, far above average industry standard, not easy to scratch or break during installation to reduce assembly waste.

3. Supplier Reliability Guarantee

We are a professional one-stop supplier of air compressor filters and spare parts with more than 10 years of industry experience. Factory direct sales eliminate intermediate markup, our diaphragms cost 15%-20% less than competitors with identical quality. All diaphragms pass four strict factory tests: high temperature aging, oil soaking, stretch fatigue and air tightness inspection, 100% qualified before shipment. All items come with 1-year warranty, free replacement for non-artificial quality defects under normal working conditions. Our professional engineers provide one-on-one size matching service for all compressor brands and models. Stable bulk supply, competitive price and reliable quality bring worry-free foreign trade procurement.
