Choose from Two Distinct Sealing Methods:

For a permanent, leak-proof seal.

O.D. Seal Transition “Wayne Design”  

Wayne TF Cutaway.jpg

O-rings sit in a grooved sleeve that encases the PE pipe’s outside wall. Within the PE pipe, a steel retainer pushes outward, compressing the pipe and creating a permanent leak-proof seal with a tensile strength far greater than the PE pipe itself.

Time-Tested Quality: Lyall O.D. Seal Transitions have been manufactured for over 30 years

I.D. Seal Transition “Lyco Design”  

Lyco TF Cutaway.jpg

A smooth sleeve encases the PE pipe, while a steel barbed spigot within the PE pipe pushes outward, hooking the pipe and creating a leak-proof seal and tensile strength that is far greater than the PE pipe itself.  

Time-Tested Quality: Lyall I.D. Seal Transitions have been manufactured for over 35 years.
