This heavy-duty accumulator diaphragm seal cup kit is customized for TOYO THBB1600-U hydraulic rock breakers, a core spare part for medium-large excavator-mounted breaking equipment. The full set includes main diaphragm cup, O-rings, retaining gaskets, backup rings and auxiliary sealing washers for complete accumulator overhaul.
Adopting imported reinforced FKM/NBR composite rubber with high-strength fiber interlayer, the product delivers outstanding oil resistance, nitrogen isolation, anti-fatigue and impact wear resistance. It perfectly matches original TOYO accessories, thoroughly solves common faults such as nitrogen leakage, insufficient impact force, abnormal pressure drop and diaphragm rupture, and greatly extends continuous service life under long-term high-frequency crushing working conditions.

Fully dimensional matched with original TOYO THBB1600-U breaker accumulator parts, consistent with OEM part numbers TOYO-THBB1600-U and SP1600080. No cutting, grinding or modification required, direct plug-and-play installation.
Core leather cup diaphragm adopts fiber interlayer FKM composite rubber, effectively resist hydraulic oil corrosion, nitrogen permeation and repeated bending fatigue. Stable flexible performance maintained in -35°C to 135°C wide temperature range, not easy to crack or deform under high-frequency impact.
All accessories pass 62MPa ultra-high pressure nitrogen sealing test. Isolate hydraulic oil and nitrogen completely, eliminate internal and external air/oil leakage, stabilize accumulator energy storage pressure, guarantee continuous stable impact power of the breaker.
Contains all sealing spare parts required for full accumulator disassembly and maintenance. One-stop matching reduces spare parts procurement cost, shortens equipment repair downtime and lowers overall operation loss.
Every diaphragm seal cup set undergoes air tightness, high pressure impact and accelerated aging fatigue tests before delivery, fully meets TOYO original equipment manufacturing standards, stable and reliable long-term construction performance.
Fit TOYO THBB1600-U hydraulic breakers equipped on multiple heavy-duty engineering machinery:
