PermaSeal® Fittings

The two-piece PermaSeal® fitting system features a fitting insert (stem) and crimp ferrule (collar). This unit is 360° radially compression crimped to hose for a positive lock that enables the assembly to be used to the maximum working pressure of the particular hose style and size without fitting pull-off or blow-off.

Two-Piece Unit for Maximum Working Pressure

Flexible Components developed the PermaSeal® Crimp Style fitting system to enable a hose assembly to be used to the maximum working pressure of the particular hose style and size. The two-piece unit -- fitting insert (stem) and crimp ferrule (collar) -- is 360° radially compression crimped to hose for a positive lock.

Fittings are locked to the Chemfluor® fluoropolymer inner tube with fitting stem grooves. The crimp ferrule compresses the reinforcing braid or rubber cover and Chemfluor® tube onto the hose barb, assuring a tight liquid/gas seal. Ferrule and stem are positively locked together with a dog-lock groove.

This carefully engineered design means hose assemblies will exceed hose pressure rating without fitting pull-off or blow-off.

All pressure ratings given are for fittings only. Consult actual hose pressure rating; use lower of hose/fitting combination to determine MAWP (maximum working pressure).

A: Sanitary style fittings (not shown) of 316L stainless steel incorporate an internal chamfer for a smooth transitional flow that minimizes pressure drop and the potential for bacteria entrapment.

B: Smooth internal finish.

C: PermaSeal® Crimp Style fittings assure a total leak-proof seal between the Chemfluor® fluoropolymer inner tube and the fitting insert, even at extreme temperature and pressure variations.

D: Smooth radial crimp won't snag on equipment or cut workers' hands.

E: Dog-lock engagement assures that ferrule and stem are totally locked together as an assembly.

F: End of hose is fully protected; no foreign material can come into contact. The cover prevents abrasion and won't allow hose to catch on sharp objects.
