Rubber Cord 0.25″ Black Solid Buna 5ft by CleverDelights

Description

Product Overview

The CleverDelights 0.25 inch solid black rubber cord is engineered for demanding industrial and hobbyist applications. Crafted from premium Buna-N (Nitrile) rubber, this cord combines a high durometer rating of 70 with a tensile strength of 1450 psi, delivering a balance of firmness and flexibility that is rare in a single‑piece cord. Measuring 5 feet in length with a precise 0.25‑inch (6.35 mm) diameter, the cord offers a consistent cross‑section that simplifies cutting, looping, and fitting into tight spaces. Its black coloration not only provides a professional appearance but also masks any surface wear, making it suitable for visible installations. The material’s resistance to gasoline, oils, greases, and a temperature span from –30 °F to 250 °F ensures reliable performance in harsh environments, from automotive workshops to outdoor field repairs. Weighing just 3.27 ounces, the cord is lightweight enough for easy handling yet robust enough to endure repeated stress cycles.

Usage

Designed for versatility, this rubber cord excels in a variety of settings. In automotive maintenance, it serves as a dependable O‑ring stock, allowing technicians to fabricate custom seals on the fly without compromising on chemical resistance. For industrial technicians, the cord’s durability makes it ideal for creating protective sleeves around sharp edges, bundling hoses, or reinforcing cable assemblies that encounter frequent movement. Hobbyists and DIY enthusiasts appreciate its ease of cutting and knotting, using it for projects ranging from custom tool handles to prototype assemblies where a resilient, non‑slipping material is essential. The cord also performs well in marine applications, where exposure to fuel and saltwater demands a material that will not degrade quickly. Its temperature tolerance permits use in both cold‑storage facilities and high‑heat environments such as engine bays, ensuring consistent elasticity and strength regardless of ambient conditions.

FAQ

What is the difference between Buna‑N and regular rubber?

Buna‑N, also known as nitrile rubber, offers superior resistance to oils, fuels, and greases compared to standard natural rubber, making it ideal for automotive and industrial uses.

Can this cord be used for outdoor applications?

Yes. The cord’s temperature tolerance and chemical resistance allow it to perform reliably in outdoor environments, including exposure to sunlight, rain, and fluctuating temperatures.

How do I cut the cord to a specific length?

Use a sharp utility knife or scissors and apply steady pressure. The cord’s consistent diameter ensures a clean cut, and the material’s flexibility prevents fraying.

Is the cord compatible with standard O‑ring sizes?

The 0.25‑inch diameter matches many standard O‑ring specifications, and the material’s elasticity allows it to be shaped into custom seal profiles when needed.

What warranty does CleverDelights provide?

We offer a one‑year limited warranty covering material defects. If you encounter any issues, contact our support team for a replacement or refund.
