Midland Industries 20855P Push-on Hose Stem Adapter

Product Description

The MIDLAND INDUSTRIES 20855P is a straight tube-to-hose adapter designed to connect a 5/16-inch push-on hose stem on one end to a 5/16-inch hose barb on the other. Constructed from polypropylene, this fitting offers corrosion resistance and is well suited for low-pressure fluid transfer applications. It is a compact, single-piece fitting used by plumbers, HVAC technicians, and general trades professionals to transition between push-on tubing and barbed hose connections in tight spaces where metal fittings are unnecessary or cost-prohibitive.

This adapter is typically installed in residential and light commercial systems where polypropylene fittings are appropriate, including water lines, condensate drain lines, and similar low-pressure fluid handling runs. The push-on stem end seats into compatible push-in tubing without tools, while the hose barb end accepts a standard flexible hose secured with a clamp. It falls within the plastic push-in fitting category and is classified as a tube-to-hose stem fitting.

Key Features

• 5/16-inch push-on hose stem connection on one end for tool-free tubing attachment
• 5/16-inch hose barb on opposite end for secure hose connection with clamp
• Polypropylene construction provides corrosion resistance and chemical compatibility with common water and drain media
• Lightweight plastic body reduces weight in fluid transfer assemblies
• Single minimum order quantity makes it practical for individual repair or replacement jobs

Compatibility

Designed as an OEM-style plastic push-in adapter for use in low-pressure fluid transfer systems requiring a 5/16-inch push-on hose stem to 5/16-inch hose barb transition.

Installation Notes

Installation is typically performed by plumbers or HVAC technicians during system assembly or repair. Shut off fluid supply and relieve line pressure before removing any existing fitting. The push-on stem end should be inserted fully into compatible push-in tubing until seated, and the hose barb end should be secured with an appropriately sized hose clamp to prevent blowoff under pressure. Verify that the fluid media and operating pressure are within the rated limits of polypropylene before installation.
