FAQ
Q1: Which breakers does this diaphragm fit?
A1: This HB30G hydraulic breaker diaphragm cup is exclusively designed for Furukawa HB30G hydraulic breakers. It is a genuine Furukawa HB30G accumulator diaphragm, durable excavator hydraulic hammer rubber diaphragm, heavy-duty heavy-duty HB30G breaker replacement diaphragm, essential HB30G hydraulic breaker spare parts, reliable excavator breaker rubber cup seal and precision OEM HB30G diaphragm assembly.
Q2: How do I know when to replace the diaphragm?
A2: Common signs of diaphragm failure include: reduced striking force, frequent nitrogen pressure loss, abnormal knocking noise, oil in the nitrogen accumulator, and complete breaker inoperability. We recommend inspecting the diaphragm every 500 working hours and replacing it every 800–1200 hours.
Q3: Why choose HNBR material over ordinary rubber?
A3: Ordinary NBR rubber hardens and cracks at temperatures above 100°C and has poor oil resistance. Our excavator hydraulic hammer rubber diaphragm uses HNBR material, which offers 3x better heat resistance, 2x better oil resistance and 4x longer fatigue life, making it ideal for heavy-duty breaker applications.
Q4: Is installation difficult?
A4: No. This OEM HB30G diaphragm assembly is a direct replacement for the original part. Basic hand tools are sufficient for installation. We provide detailed installation instructions and video guidance to ensure proper fitting.
