Furukawa HB20G Hydraulic Breaker Seal Kit Rubber Diaphragm Wear Resistant

Our HB20G hydraulic breaker seal cup acts as a durable Furukawa HB20G rubber diaphragm and reliable high-pressure hydraulic breaker seal. This premium wear-resistant HB20G breaker cup is engineered as a professional HB20G breaker accumulator seal, a standard OEM HB20G hydraulic seal part and a robust heavy-duty rubber seal for HB20G, tailor-made exclusively for Furukawa HB20G hydraulic breakers. It effectively maintains steady nitrogen pressure and stops hydraulic oil leakage during continuous operation. Manufactured from premium NBR or PU compound via professional vulcanization process, this seal delivers excellent pressure resistance up to 60–125 MPa, alongside superior heat and aging resistance within the temperature range of -40℃ to 140℃. It withstands persistent impact and vibration commonly seen on mining, quarrying and demolition sites. With precise OEM dimensions of 169*36.6 mm, it fits perfectly into the HB20G accumulator and eliminates oil seepage, gas loss and power drop caused by poor sealing. As a direct replacement component, this OEM HB20G hydraulic seal part requires no on-site modification, helping you cut downtime and overall maintenance expenses. Every wear-resistant HB20G breaker cup goes through full factory inspection to guarantee stable and long-lasting performance under harsh working conditions.

1. Q1: Which hydraulic breaker does this seal part fit?
   A1: This professional HB20G hydraulic breaker seal cup is developed exclusively for Furukawa HB20G hydraulic breakers. It functions as a standard Furukawa HB20G rubber diaphragm, high-pressure hydraulic breaker seal, wear-resistant HB20G breaker cup, HB20G breaker accumulator seal, OEM HB20G hydraulic seal part and heavy-duty rubber seal for HB20G.
2. Q2: What issues will occur if the seal cup is worn out?
   A2: A damaged wear-resistant HB20G breaker cup will cause nitrogen leakage, hydraulic oil seepage, reduced striking force and frequent equipment shutdown. Replacing it with a new HB20G hydraulic breaker seal cup can fully restore normal working performance.
3. Q3: What is the typical service life of this product?
   A3: Under regular operating conditions, this high-pressure hydraulic breaker seal can last 3 to 6 months. Its premium raw materials deliver longer service life compared with ordinary aftermarket parts.
4. Q4: Is the installation process complicated?
   A4: Not at all. This HB20G breaker accumulator seal adopts OEM standard dimensions for direct installation. No special tools or modifications are required.
5. Q5: Which material is recommended for heavy-duty working scenarios?
   A5: For mining and high-impact operations, we suggest choosing the PU version of this heavy-duty rubber seal for HB20G, which features better pressure and wear resistance.
