EHLE's replacement parts are made with precision joints and EHLE are rightly proud of them. Technically speaking, these 18.8 joint size EHLE puncture-hole diffusers leave nothing to be desired.
The joint walls are twice as thick in comparison to common industrial joints.
The ringless, rounded rims of EHLE joints on both pipes and parts will pardon one or two ungentle knocks.
