## Description

Choosing air-line fittings is easier when the job calls for a range of tube sizes rather than one specific connection. This Ruikarhop set brings multiple push-to-connect sizes together for pneumatic setups and workshop tasks.

The circular release ring lets you insert or remove compatible tubing without tools. That makes it practical to assemble or adjust an air line as your setup changes.

With 180 fittings, a tube cutter and a storage case, the set keeps a varied selection of connectors together for ongoing projects and repairs.

## Worth noting

The fittings are designed for PP, PU, PA, PE and PVC tubing, with listed sizes from 1/8 to 1/2 inch and 4 to 12 mm. That range is useful when a project involves different tube diameters: instead of building a supply one size at a time, you can choose a connector to match the tubing on hand. The sizes are stated in both imperial and metric measurements.

A push-to-connect design makes the connection process straightforward. Insert the tube into the fitting, then use the circular release ring when it is time to remove it. The internal locking spring is designed to hold the connection, and the stated working pressure is 0–1.0 MPa (0–145 psi), with a working temperature range of 0–60°C (32–140°F). The fittings combine nickel-plated brass with PBT plastic, bringing metal and plastic components into one connector design.

The assortment is intended for pneumatic applications such as industrial automation, automotive workshops, air suspension and pneumatic tools. A tube cutter and plastic case are included, so the kit provides useful accessories for preparing and organizing a selection of fittings.

## Practical tips

Match the fitting size to the tubing’s outside diameter and confirm that the tube material is PP, PU, PA, PE or PVC before making a connection. Use the included cutter to prepare tubing for the connection, then insert it into the push-to-connect fitting. To release the tube, press the circular ring. Keeping the fittings grouped in the case can make it easier to find a suitable size when moving between jobs.

## Who it’s for

This set is suited to people assembling or maintaining pneumatic lines across more than one tube size, including workshop users and those working with air tools or automation equipment. It also makes sense for a repair kit where having several connector sizes ready is more useful than keeping a single size on hand. If your work involves compatible tubing in the listed materials, the assortment offers flexibility across different connection needs.

## What to clarify

**Which tubing materials are compatible?** The fittings are listed for PP, PU, PA, PE and PVC tubing. Choose a connector that matches the tube’s size as well as its material.

**How do the fittings connect and release?** They use a push-to-connect design: insert the tubing into the fitting, then press the circular release ring to remove it. The connection is supported by an internal locking spring.

**What pressure and temperature ranges are stated?** The working pressure is 0–1.0 MPa (0–145 psi), and the working temperature range is 0–60°C (32–140°F).

## When it makes sense

Choose this assortment when a pneumatic project calls for several tube diameters and you want the fittings, a cutter and storage in one kit. Its range of compatible tubing materials and push-to-connect design make it a practical fit for workshop air lines, equipment maintenance and other compatible pneumatic setups.
