1141
Series are general purpose couplings that connect under
pressure for high pressure applications. The 1/4 inch stainless
steel coupling connects together with a threaded brass sleeve.
Polyurethane seals resist extrusion and abrasion.
Features:
• 303
stainless steel body
•
Rated pressure up to 10,000 psi and 17,000 psi intermittent
pressure
•
Small diameter mating seal keeps separation forces to
a minimum, allowing easier threaded connection and
disconnection at pressures up to 5,000 psi
•
Polyurethane seals to resist extrusion and abrasion
•
Self locking threads guard against accidental disconnection
•
Visual connection indicator – when fully coupled, sleeve edge
is flush with the end of the male thread
•
Standard end configuration is female pipe thread
•
