Universal Fittings

Poly pipe comes in specific outer diameters and inner diameters. Universal fittings sized ½” to 1” allow you to use one fitting for some slight variations in size. For example, one fitting will allow you to connect to both 0.700” and 0.710” OD tubing. That would not be possible with most compression or barb fittings. Universal fittings are often reusable.
