A comprehensive guide to Original Equipment Supplier parts and why they represent the smart choice for equipment owners
The Hidden Truth About Equipment Parts: Same Factory, Different Label
When your heavy equipment needs replacement parts, you’re faced with a choice that can significantly impact both your budget and operational efficiency. Most equipment owners assume they must choose between expensive “genuine” branded parts or potentially inferior aftermarket alternatives. However, there’s a third option that delivers OEM quality at a fraction of the cost: Original Equipment Supplier (OES) parts.
What Are OES Parts?
Original Equipment Supplier (OES) parts are genuine components manufactured by the exact same suppliers that produce parts for major equipment brands like Caterpillar®. These are not aftermarket copies or reverse-engineered alternatives — they are identical parts made in the same factories, using the same specifications, materials, and quality control processes, but sold without the premium brand markup.
The Key Distinction:
- OEM Parts: Made by original suppliers, branded and distributed by equipment manufacturers (Caterpillar®, etc.)
- OES Parts: Made by the exact same original suppliers, distributed independently
- Aftermarket Parts: Made by third-party manufacturers with varying quality standards
The ENCOPARTS Story: Born from Industrial Excellence
Origins in Brazil’s Industrial Heartland
ENCOPARTS’ journey began nearly 30 years ago in Piracicaba, São Paulo, Brazil — a city that would become synonymous with heavy equipment manufacturing excellence. This wasn’t coincidental timing; it was strategic positioning at the epicentre of South America’s industrial transformation.
In 1954, Caterpillar® established its first South American manufacturing facility in Brazil, initially as a parts and components operation in São Paulo before expanding to full production in Piracicaba. This marked the beginning of what would become one of the world’s largest heavy equipment manufacturing complexes outside the United States.
The Birth of a Supply Chain Ecosystem
As Caterpillar’s® Piracicaba plant grew — eventually employing over 5,000 people and manufacturing 28 different machine models including hydraulic excavators, wheel loaders, motor graders, and track-type tractors — something remarkable happened. Local suppliers and manufacturers began establishing operations in the region to support this massive industrial complex.
This is where ENCOPARTS was born.
Our founders recognised the extraordinary opportunity created by Caterpillar’s® presence in Piracicaba. As local manufacturers and suppliers emerged to serve the plant’s needs, ENCOPARTS positioned itself to build direct relationships with these original equipment suppliers. What started as connections with local Brazilian manufacturers evolved into partnerships with multinational corporations as the supply chain expanded globally.
From Local Relationships to Global Network
Over nearly three decades, ENCOPARTS has cultivated relationships with over 400 original equipment suppliers worldwide, the same manufacturers that produce components for Caterpillar® equipment. This network extends far beyond Brazil, encompassing suppliers in the United States, Europe, and Asia.
Today, ENCOPARTS can supply approximately 70% of all Caterpillar® part numbers in existence — a testament to the depth and breadth of our original supplier relationships.
The Quality Advantage: Same Standards, Better Value
Identical Manufacturing Standards
When you purchase OES parts from ENCOPARTS, you receive components that are:
- Manufactured in the same facilities as OEM parts
- Made to identical specifications and tolerances
- Subject to the same quality control processes
- Composed of the same materials and components
- Tested to the same performance standards
The Only Difference? The Label
The fundamental difference between OEM and OES parts is branding and distribution channels. OEM parts carry the equipment manufacturer’s label and are sold through their authorised dealer network at premium prices. OES parts are the identical components sold directly by the original suppliers at competitive prices.
Applications Across Industries
ENCOPARTS supplies OES parts and components exclusively for use on Caterpillar® equipment across diverse market sectors:
- Mining: Critical components for excavators, haul trucks, and processing equipment
- Construction: Parts for bulldozers, motor graders, and compaction equipment
- Agriculture: Components for tractors and harvesting machinery
- Marine: Parts for marine engines and auxiliary systems
- Forestry: Specialised components for logging and timber processing equipment
- Energy: Parts for power generation and oil & gas applications
The Economic Impact of Choosing OES Parts
Cost Savings Without Compromise
By eliminating brand markups and dealer margins, OES parts typically cost 20-50% less than equivalent OEM parts while delivering identical quality and performance. For fleet operators and equipment owners, this translates to:
- Reduced maintenance budgets without sacrificing reliability
- Improved ROI on equipment investments
- Maintained resale values through proper maintenance with quality parts
- Predictable operating costs through consistent part quality

- Agricultural operators maximising equipment uptime during critical seasons
- Fleet managers optimising total cost of ownership across multiple machines
The Future of Equipment Parts
Industry Trends
The equipment parts industry is evolving toward greater transparency and value-focused purchasing decisions. Equipment owners are becoming more educated about the reality that:
- Brand names don’t determine quality — manufacturing standards do
- Premium pricing often reflects marketing costs rather than superior quality
- Original suppliers are the true source of quality, regardless of branding
- Total cost of ownership matters more than initial part prices
ENCOPARTS’ Commitment
As the industry evolves, ENCOPARTS remains committed to:
- Expanding our supplier network to serve more equipment types and applications

- Supporting customers with technical expertise and superior service
Conclusion: Quality You Can Trust, Value You Can’t Ignore
The choice between OEM and OES parts isn’t really about quality — when sourced from reputable suppliers like ENCOPARTS, the quality is identical. The choice is about value, transparency, and making informed decisions based on facts rather than brand marketing.
OES parts represent the perfect intersection of uncompromising quality and economic efficiency.
When you choose ENCOPARTS OES parts, you’re not compromising on quality — you’re choosing the same quality without paying for brand premiums. You’re getting parts manufactured by the same suppliers, to the same specifications, with the same materials, backed by nearly three decades of supplier relationships and industry expertise.
The smart choice is clear: Same quality, better value, superior service.
