SP Bel-Art 5 in 1 Tubing Connectors 3½in Polypropylene 12‑Piece Set

Description

Product Overview

The SP Bel-Art 5 in 1 Straight Tubing Connectors are engineered to meet the demanding requirements of modern laboratory and industrial fluid handling. Crafted from high‑grade polypropylene, each connector offers chemical resistance, durability, and the ability to withstand repeated autoclave cycles at 121 °C (250 °F). The set includes twelve pieces that cover five standard tube diameters—9/16″, 1/2″, 7/16″, 3/8″ and 5/16″—allowing you to connect identical tubing or reduce from a larger to a smaller size within the same range. All connectors feature NPT (National Pipe Thread) male threads, ensuring a secure, leak‑free seal when mated with compatible fittings. The compact packaging dimensions (6.26 x 5.51 x 1.46 inches) and lightweight design (49.9 g per piece) make storage and inventory management effortless. Designed by Bel‑Art Products and marketed under the SP Scienceware brand, this 5‑in‑1 solution has earned a solid reputation, reflected in a 4.1‑star rating from 25 customer reviews and a top‑20 ranking in the Microbore Tubing Connectors category.

Usage

These connectors excel in a variety of environments where precise fluid control is essential. In research laboratories, they are commonly used to assemble microbore tubing networks for chromatography, spectroscopy, and sample preparation systems. Their autoclavable nature ensures that the entire fluid path can be sterilized without compromising the integrity of the connectors, making them ideal for microbiology, cell culture, and pharmaceutical applications. In industrial settings, the connectors serve as reliable components in pneumatic and hydraulic circuits, providing quick and secure transitions between tubing sections of differing diameters. The NPT threading simplifies installation for technicians, while the polypropylene construction resists corrosion from aggressive chemicals, solvents, and cleaning agents. Whether you are configuring a custom fluid delivery system, retrofitting an existing setup, or building a new experimental rig, these connectors deliver consistent performance and reduce the need for multiple specialized parts.

Why Choose Us

Choosing the SP Bel-Art 5 in 1 Straight Tubing Connectors means investing in a product that combines engineering excellence with practical convenience. Each connector undergoes rigorous quality control testing to verify dimensional accuracy, thread integrity, and material consistency. The polypropylene formulation is specifically selected for its high melt flow index, enabling smooth internal flow and minimizing pressure drop across the connector. Autoclave compatibility eliminates the need for disposable alternatives, supporting sustainable laboratory practices and reducing long‑term costs. Our commitment to customer satisfaction includes responsive technical support, detailed product documentation, and a straightforward return policy should any issues arise. By consolidating five connector sizes into a single, compact set, we help you streamline inventory, simplify ordering processes, and free up valuable bench space.

FAQ

Can these connectors be used with metal tubing?

While the connectors are designed for polypropylene and similar polymer tubing, they can be used with metal tubing that has compatible NPT threads, provided the inner diameter matches the connector’s size range.

What is the maximum pressure rating for these connectors?

The connectors are rated for typical laboratory pressures up to 150 psi. For higher‑pressure applications, consult the manufacturer’s technical data sheet for specific limits.

Are the connectors compatible with standard laboratory clamps?

Yes, the connectors can be secured with standard hose clamps or tubing clips, making them easy to integrate into existing setups without additional hardware.

How many autoclave cycles can the connectors endure?

Polypropylene connectors are tested to withstand at least 50 autoclave cycles at 121 °C without degradation of mechanical properties or dimensional stability.
