Our 7 Strand Core 4mm Solid Blue 550 Polyester Paracord is designed for outdoor, marine, tactical, and industrial applications that require dependable strength and long-term weather resistance. Manufactured by T&T Outdoor, it is available for OEM, wholesale, bulk orders, and private label projects, with custom lengths and packaging options to meet different market requirements.
7 Strand Core 4mm Solid Blue 550 Polyester Paracord is a heavy-duty braided utility cord designed for reliable performance in demanding environments.
Genuine 7-core construction for dependable tensile strength and durability.
550 lb minimum breaking strength with a standard 4 mm diameter.
100% polyester construction with low stretch and excellent moisture resistance.
Solution-dyed solid blue color for improved color retention during long-term outdoor use.
UV- and abrasion-resistant braided sheath for enhanced service life.
Suitable for camping, marine equipment, tactical gear, emergency kits, utility lashing, DIY projects, and outdoor accessories.
Available from T&T Outdoor with OEM, ODM, wholesale, and bulk supply services.
Authentic 7-Core Construction – Engineered with seven independent inner strands and a tightly braided 32-carrier polyester sheath, delivering dependable structural integrity and consistent load distribution. Each 4mm paracord core is twisted from multiple high-tenacity yarns for maximum strength.
Superior UV Resistance – Compared with conventional nylon cords, this 550 polyester paracord offers exceptional resistance to sunlight degradation, making it ideal for extended outdoor exposure. Maintains performance integrity for 3-5 years in direct sunlight.
Low Stretch Performance – Polyester maintains excellent dimensional stability under load, reducing sagging and improving tension retention. Only 10-15% elongation at break versus 30%+ for nylon – critical for applications requiring consistent tension.
Water & Moisture Resistance – Absorbs minimal moisture (≤0.5%) and dries rapidly. Perfect for marine environments, rainy camping trips, and humid industrial settings. Will not become heavy, stiff, or compromised when wet.
Vivid Solid Blue Color – Produced using solution-dyed polyester technology for exceptional color consistency and enduring appearance. The blue permeates every fiber – not just a surface coating. Ideal for marine applications where visibility against water matters.
32-Carrier Braided Sheath – Dense, tight braid produces a smoother, rounder, more abrasion-resistant sheath than cheaper 16- or 24-carrier alternatives. This 7 strand core 4mm solid blue 550 polyester paracord feels premium and performs reliably under demanding conditions.
8.5g/m Weight – Full material density for proper 4mm 7-core polyester paracord. Lighter cords (6-7g/m) use fewer or thinner yarns – resulting in weaker performance. T&T Outdoor 550 polyester paracord delivers the full material specification.

Q1: Does this 4mm paracord really meet the 550 lb standard?
Yes. This 550 polyester paracord features true 7-core construction and is batch-tested to minimum 550 lb (250 kg). Test reports available for wholesale buyers.

Much slower than surface-dyed cords. Solution-dyed polyester maintains its color significantly longer – 3-5 years of outdoor exposure. T&T Outdoor blue 4mm paracord is engineered for lasting vibrancy.
Q3: Does the blue color bleed or transfer?
No. The color is integrated into the polyester fibers, not surface-applied. It will not rub off, bleed, or stain hands, clothing, or equipment.
Q4: Is this cord suitable for saltwater marine use?
Yes. Polyester resists saltwater degradation, UV damage, and moisture absorption. Blue is a traditional and visible color for dock lines, fender ties, and marine utility.
Q5: Can this cord be used for climbing or life-safety?
No. Not certified for climbing, rappelling, rescue, or fall protection. Utility use only – camping, lashing, crafts, marine, industrial.
