Large Flexible Rubber Couplings - 4" Clay x 4" C.I. PVC Flexible Rubber Coupling

Large Flexible Rubber Couplings. These kind of PVC Couplings (all 100mm long) can be used to successfully join pipes both below and above ground. They are especially convenient when joining pipes made of dissimilar materials or where no standard pipe coupling is available. Pipes are joined by inserting both ends into the flexible coupling and tightening the two stainless steel clamping bands. They are ideally suited to low pressure drain waste and venting applications.
