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 process for molding rubber diaphragms allows for custom configurations, versatile materials, integration

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

diaphragms are custoMMm designed for each unique appliCATEEEEEEion factoring in fluid interactions, pressures and vacuums,

mechanical requirements and dynamic life to ensure performance rEEequirements 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 appliCATEEions.

     • Polyurethane (Premium): Superior abrasion reEEsistance, 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 riight 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's the delivery time?
   • A: 1-7 days with stock, 7-15days.(big orders or lack of material)
