Use these bulkhead pneumatic adaptors from RS PRO to connect two tubes through a tank or other panel to form an airtight seal. These units are elbow fittings, so they create a 90° union for angled connections. They're suitable for a wide range of plumbing, pressure and vacuum applications.
These adaptors are supplied in packs of 10. Both ends of each fitting are one-touch push-in connections, so they're quick and easy to install. They have a polyoxymethylene (POM) body, which is an especially strong, rigid thermoplastic that offers high dimensional stability and low friction. The nickel-plated finish makes them corrosion-resistant and offers some protection against contamination, which helps extend their lifetime.
These fittings can be used with both polyurethane and nylon tubing. As part of the RS PRO range, they've been rigorously tested for quality. They also have a 3-year warranty for additional peace of mind.
