Advantages
Metru-Lok™ is a one-piece, ready-to-use, bite-type ftting for use with
either copper or plastic tubing. The ferrule is held captive in the nut.
The ftting is designed to permit tube entry and ftting makeup without
removal of the nut and ferrule, avoiding the assembly of the ftting
components prior to use.
Fitting ready to use
• Compact fully assembled ftting, timesaving at makeup.
• Captive snap in ferrule.
• Simplifed handling and stock-keeping.
• No presetting of the ferrule necessary.
Positive sealing and bite
• The wedging action of the nut when tightened causes the ferrule
to bite into the outside diameter of the tube wall for a leakproof
connection.
• With fexible tubing (polyurethane, PEBA or polyethylene), it is
recommended to use a tube insert for a positive holding of the tube.
Safety
• Visible ferrule (extending to rear of nut) allows quality control checks
for correct assembly.
Parker Metru-Lok™ Fittings
Excellent vibration resistance
• Vibration is contained by the rear compression of the ferrule
extending outside the nut.
• The tube is held at the bottom of the ftting.
• The tube is thus held between the above two points so that vibration
running along the tube does not affect the sealing and bite area.
How to Use: Assembly
• Cut the tube square.
• De-burr (copper tube).
• Insert the tube through the nut and ferrule until it bottoms.
• Finger tighten the nut.
• Wrench tighten the nut one turn, or one and one half turns,
according to size.
Disassembly - remake
• The Metru-Lok™ ftting can be assembled and disassembled at least
15 times. At each remake, hand tighten the nut, then wrench tighten
1/16 of a turn.
