Product Overview
This heavy‑duty accumulator cup seal and diaphragm assembly is engineered for Sandvik HLX5 / HLX5T hydraulic rock drifters. It includes high‑performance rubber diaphragm, pressure cup seal and auxiliary sealing gaskets for accumulator overhaul service.
Manufactured from imported high‑strength FKM / reinforced NBR rubber compound, the parts deliver outstanding fatigue resistance, impact resistance and hydraulic‑oil compatibility. It serves as a direct replacement for original Sandvik rubber components, solving typical failures such as accumulator air leakage, pressure fluctuation and percussion power drop, extending drifter service life under harsh underground mining and tunneling working conditions。

Key Selling Points
1. 100% Exact OEM Replacement.
Fully interchangeable with original Sandvik HLX5 / HLX5T hydraulic rock drifter. Matches OEM part numbers 09260298 and 15225488. Direct installation without any mechanical modification。
2. Heavy‑Duty Reinforced Rubber Material.
Core diaphragm and cup seal adopt high‑toughness FKM and reinforced NBR formula. Excellent anti‑fatigue, anti‑aging and oil‑resistant performance, stable operation within‑25°C ~ 110°C mining environment. Resists frequent high‑frequency percussion impact load.
3. Stable Pressure & Zero Accumulator Leakage.
All sealing components are tested under 25 MPa cyclic pressure. Effectively prevents gas‑oil mixing and accumulator internal/external leakage, maintains steady striking pressure and consistent rock drilling output power. Reduces frequent accumulator re‑charging work.
4. Complete Accumulator Overhaul Assembly.
Contains all rubber sealing accessories required for low‑pressure and stabilizer accumulator maintenance of HLX5 / HLX5T drifter. Integrated spare‑parts set shortens field repair downtime and cuts overall equipment operating costs.
5. Strict Factory Quality Control.
Every batch of cup seal & diaphragm passes cyclic pressure fatigue test, air tightness test and aging inspection before delivery. Meets OEM performance standard, ensures reliable long‑term underground industrial operation.
6. Application Scope.
Specially designed for Sandvik HLX5 / HLX5T hydraulic rock drifter equipped on various heavy‑duty underground engineering equipment:
• Underground tunneling drill jumbos
• Mine development drilling rigs
• Underground bolter and excavation machinery
• Metal & non‑metal underground mining equipment
• Hydraulic rock drilling production systems
• High‑frequency percussion underground mobile drill rigs
