>B< Press XL has only two internal parts, the grip ring and the seal. Both parts have an internal diameter larger than the tube, which allows for easy tube insertion and pre press leak indication.
The seal is not easily displaced by tube insertion. Triple point seal on the post pressed fitting body counters any pressing distortion. Greater seal contact area on tube. Self setting seal area for correct function of seal. Seal security and longevity increased as a result.
Complete diameter grip with equally spaced collapse zones ensures all round equal grip on the tube diameter and even seal compression between tube and fitting after pressing.
