Cerrobrass HM-4 Brass Hose Insert 1/4 Inch Barbed Fitting

Product Description

The CERROBRASS HM-4 is a brass hose insert fitting designed for low-pressure fluid transfer applications requiring a secure, leak-resistant barbed connection. Constructed from brass, this hose insert accepts 1/4 inch inside diameter hose and uses a hose barb x hose barb end connection to join two sections of flexible hose. At 2.03 inches in overall length and weighing just 0.017 pounds, it is a compact, lightweight component. The rated temperature range spans -40 degrees F to 160 degrees F, making it suitable for a range of fluid handling tasks in plumbing, HVAC, and general trade applications. Licensed plumbers and HVAC technicians are the typical installers.

This fitting is used in residential and light commercial settings where 1/4 inch ID flexible hose must be joined inline. Common applications include condensate drain lines, low-pressure water supply connections, and similar fluid transfer systems where a barbed brass insert provides a reliable mechanical grip on the hose. The hose barb x hose barb configuration eliminates the need for threaded fittings at both ends, simplifying the connection in tight or confined spaces.
