Why Choose Us?

A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure

effects to cross the barrier but not the material being contained.
Common uses for diaphragm seals are to protect pressure sensors from the fluid whose pressure is being measured.
Koko Shop / Huilian provides customers engineered solutions for rubber diaphragm appliCATEEEEEions across many industrie.

Koko Shop / Huilian process for molding rubber diaphragms allows for custom configurations, versatile materials, integration

of reinforcement in the rubber compound and the ability for in-mold bonding of metal or plastic substrates. Our rubber

diaphragms are custom designed for each unique appliCATEEEEEEEion factoring in fluid interactions, pressures and vacuums,

mechanical requirements and dynamic life to ensure performance requirements are achieved.

FAQ:

1. Q1: What materials are your breaker seals (especially the main piston seal/u-cup) made of? Why is this important?

   • A: Our seals are primarily made from High-Grade Nitrile Rubber (NBR) or Polyurethane (PU/AU), chosen for their critical properties:

     
     

     • NBR (Standard): Excellent resistance to hydraulic oils (mineral & synthetic), good abrasion resistance, wide temperature range (-30°C to +100°C), cost-effective. Ideal for most standard applications.

     • Polyurethane (Premium): Superior abrasion resistance, higher tensile strength, better extrusion resistance under high pressure/pulse, good oil resistance. Recommended for high-impact, high-pressure breakers or harsh conditions.

     • Importance: The right material ensures longevity, prevents leaks, maintains hammer efficiency, and avoids costly downtime and oil contamination.

     
     

   • Q2: What warranty do you offer on your hydraulic breaker seal kits?

     
     

     • A: We offer a 【3 months】 warranty against manufacturing defects (e.g., material flaws, incorrect dimensions) from the date of shipment.

     • 
       

     • Q3: What critical seals are included in the BRV43 kit?
       A: The kit contains all seals required for a full rebuild:

     • Main Piston U-Cup (Nitrogen & Oil Side)

     • Upper/Lower Chamber Seals

     • Accumulator Piston Seals & O-rings

     • Valve Block Seals

     • Wiper Seals (Dust Guards)

     • Backup Rings (Anti-Extrusion)

     • All gaskets and specialty O-rings.

   • Q3: What's the delivery time?
