Crown Rubber Works – Wiper Seals Manufacturer, Supplier & Exporter (India → Papua New Guinea)

rown Rubber Works is a leading manufacturer, exporter, and supplier of Wiper Seals from India to Papua New Guinea, serving industries that rely on high-performance hydraulic and pneumatic systems.

Our Wiper Seals are engineered to prevent dust, dirt, and contaminants from entering the hydraulic cylinder assembly — protecting internal components like Rod Seals, Piston Seals, and Guide Rings from premature wear and leakage.

We design each profile to deliver maximum contamination control, low friction, and long service life even in extreme Afghan environmental conditions — dusty, dry, or rugged. From standard profiles to custom-engineered wipers, we deliver quality that meets global hydraulic sealing standards and Papua New Guinea’s market needs.

Why Choose Crown Rubber Works for Wiper Seals

• Contamination Control Expertise:
  Designed to scrape and clean the rod surface before re-entry, ensuring dust and mud cannot damage internal seals.
• Advanced Polymer Compounds:
  Materials such as Polyurethane (PU), Nitrile Rubber (NBR), FKM (Viton®), and PTFE blends ensure performance across a wide temperature and fluid range.
• Precision Manufacturing:
  Tight dimensional control on outer diameter interference, lip preload, and surface finish compatibility ensures a perfect fit and reliable function.
• Custom Profiles for Afghan OEMs:
  Custom-made profiles to fit rod grooves, metal scrapers, or integrated dust seal assemblies for construction, agriculture, and transport machinery.
• Ready for Harsh Conditions:
  Seals designed to resist sand, dust, water, and mud, making them ideal for Papua New Guinea’s rugged terrain and weather.
• Export-Ready to Papua New Guinea:
  Moisture-protected export packaging, COO, packing list, and HS codes provided with all shipments — via air or land freight.
• Competitive Value:
  High-quality, long-lasting performance at economical landed cost for Afghan OEMs, distributors, and MRO buyers.

Wiper Seals – What They Do

Wiper seals (scraper seals) are installed in the cylinder head to wipe the piston rod clean as it retracts into the hydraulic cylinder.

• Prevent ingress of dust, dirt, mud, and water
• Protect rod seals and internal components from wear
• Maintain seal performance and service life
• Ensure smooth rod motion without contamination buildup

When combined with Rod Seals, they form the frontline defense of the hydraulic sealing system.

Sub-Categories of Wiper Seals

A) Single-Lip Wiper Seals:

• CA1 Wiper Seals: Standard polyurethane profile for general hydraulics; high wear resistance and effective scraping.
• CA3 Wiper Seals: Single-acting PU wipers with flexible lips; suitable for dry and dusty conditions.
• CA4 Wiper Seals: Compact, easy-fit design; compatible with snap-in grooves; good dust removal.
• CA11 Wiper Seals: Dual-lip elastomer type with improved rod protection; ideal for mobile equipment.
• CA15 Wiper Seals: Wide lip for aggressive scraping; good for agricultural and mining cylinders.
• CA16 Wiper Seals: Robust lip profile with tight OD fit; prevents moisture and abrasive intrusion.
• CA17 Wiper Seals: Designed for heavy-duty and long-stroke cylinders; high resistance to abrasion and environmental stress.

B) Double-Lip Wiper Seals:

• Metal-Cased Double-Lip Wipers: PU or NBR sealing element bonded to metal case; provides enhanced stability and protection.
• PTFE Pneumatic Rod Seals: Ultra-low friction for precision actuators and high-speed automation.
• Rubber-Metal Composite Wipers: Effective in industrial machinery where high pressure washing or mud contamination is common.

C) Special Wiper Assemblies:

• Combination Wipers (Wiper + Rod Seal): Integrated seal units combining wiper and secondary sealing lip for compact design.
• Spring-Energized Wipers: PTFE-based seals with metallic energizers for critical environments.
• Metal Scraper Rings: For cylinders exposed to stone, gravel, or metal chips - mechanical scraping protection.
