How Tight Is Tight? SAE Fittings: Assembling Adjustable Elbow Fittings

Live from our newest Colliflower ParkerStore in Trenton, NJ is the second installment in our web series: "How Tight Is Tight?". This quick instructional video features SAE fittings. Colt shows you how to avoid O-ring damage and leakage issues that usually occur when under or overtightening your SAE fittings.


Watch the video and follow the steps below for additional reference:

1. Inspect your tapered fitting threads for any damage, dents, or scratches, which can make installation difficult or create a leak path.

2. Lubricate the O-ring using preferred method, such as hydraulic fluid.


3. Backoff lock knot so it cannot move. 


4. Fully thread into port thread.


5. Back off to desired angle - no more than one full turn.


6. Move wrench to turn the lock knot down. This seals the O-ring to prevent leakage.


7. To ensure correct torque specifications, refer to the 4300 Parker catalog (see below document for reference):
