The Uni-Cup Pig is manufactured as a single piece construction with no small parts. Three cups are molded along the body providing a good flexible seal. This style pig is used where more flexibility is required such as pipeline with varying wall thickness, low flow, or low pressure applications.

This pig is made of Inline’s MAXITHANE®, a higher performing polyurethane. Various durometers are also available to meet specific job requirements.
