Dear Manager,

I hope this email finds you well.

My name is Jihyun WOO, CEO of EVERTECH CORPORATION, a leading manufacturer and supplier of advanced pipe joints based in South Korea.

I am writing to propose a strategic business opportunity and introduce our innovative product, 'Hookjoint', specifically engineered for the global air conditioner market.

This is a technique, not magic.

The world's first and best highly flexible stainless steel piping for refrigerants (PossFD) and the one-touch "HookJoint" connection system.

Why Choose Hookjoint?

■ Flame-Free, One-Touch Connection:

'Hookjoint' is a breakthrough one-touch insert type joint that eliminates the need for welding or open flames, creating a new paradigm for air conditioning piping work.

■ No Special Tools Required:

Unlike competing products such as 'LOKRING' or 'ZOOMLOCK', which require specialized equipment or mechanical force, 

Hookjoint offers a highly differentiated, tool-free installation experience.

■ Certified Innovation & Quality:

This new product has been recognized for its outstanding performance, securing both global UL certification 

and the prestigious NET (New Excellent Technology) certification from the Korean government.

■ Premium Material Collaboration:

While copper has traditionally dominated the market, we have collaborated with POSCO—a world-class global iron and steel maker—to develop 

and commercialize a new high-elongation, high-flexibility stainless steel tube tailored for this system.

We would welcome the opportunity to discuss how our solutions can bring meaningful value to your upcoming projects. 

Please feel free to reply directly to this email or contact us at your earliest convenience.

If there is another department or team member within your organization who manages components and procurement, 

we would highly appreciate it if you could forward this message to the right person.

Thank you for your time and consideration. We look forward to the possibility of collaborating with you.

Best regards,

Jihyun WOO CEO, EVERTECH CORPORATION
