Pushlox Locking Fittings

  Pushlox allows your existing lines or hoses to be threaded, sealed and locked into place by hand. A videotaped test shows an SNS Designz -12  locking fitting to hold well over 12,000-lbs. psi without leakage, and only hand tight. With the Progressive Rotational Sealing System (PRS), leaks or weeping at the hose end or fitting connection are a thing of the past. Why take a chance on any fluid connection coming loose.

 1. Locks the Hose end Nut in place.                                              1. Thread on.
 2. Retrofits to your existing hose end connection.                        2.Require a wrench to seal the connection 
 3. Eliminates cross-threading.                                     
 4. Prevents cavitation.
 5. Stays as a unit, no assembly required.
 6. Protects threads from F.O.D. (Foreign Object Damage).
 7. Eliminates the need for safety wire.
 8. Reduces R & R time.
 9. Increased safety factor.
10. The PRS sealing system
11. Eliminates unscheduled maintenance.
12. Eliminates hose twisting or binding.
13. Greatly reduces contamination at the connection.
14. Eliminates over tightening the connection due to sealing system.
15. Allows for torsional flex without losing the seal at the connection.
16. Standard B-Nut is accessible to be torqued before locking.
17. Can be made tamper proof by filling the lock ring hole with a suitable material, such as silicone or epoxy.
18. Can only be hand tightened.
19. Eliminates unnecessary contamination to the environment (leaks).
20. The hose end may be "Timed" or "clocked" in order to position  the release tang away from any vulnerable areas.
21. The Full Knurl locking sleeve allows for more than the double the griping surface of any similar products.
22. The release tang pocket protects the release tang of the locking ring from damage that may be caused by an impact  or misuse from tools or debris.
23. In the event an object should strike the sleeve in the unlocked position, the sleeve will absorb the impact of F.O.D. by snapping out of the unlock detent.
24. Allows the installer the ability to "Spin" the hose end on and off without the use of fingers.

The Pushlox Locking fitting is a product that is designed to lock your threaded 37º degree hose end to the mating fitting body. The Concept is adaptable to any threaded connector. This version retains 95% of the dimensions that are currently in use in the AN system

                                     The device is made up of 4 components.

                                      1.The main fitting body         
                                      2.The locking sleeve 
                                      3. The lateral displacement locking ring (LD lockring) 
                                      4. Progressive Rotational Teflon seal.
 

Upon initial contact of the inner taper of the 37º B nut creates the initial seal by a tightening rotation of the B nut towards the main fitting body. When the B nut is rotated to fully compress the seal, the system is then pressurized and the seal expands outwardly. Since outward movement is limited by the captive parameters of the fitting body the seal is forced to travel axially against your hose end or B nut.

In the beginning...

The AN  37º system of fluid fittings was designed in the early 1940's and is still used today in thousands of applications. Mainly designed for aircraft use, the connections were designed to be "safety wired.
A report on fluid connection failures obtained through the F.A.A. has been the inspiration for the new Pushlox Locking Fitting. For years the industry has tried to come up with a "better mouse trap" to make the maintenance of fluid systems faster, easier and safer. The Pushlox Locking fittings are all that and more!

The Pushlox Locking fitting is unrivaled in the Hi-Performance automotive industry. Even the Higher end race teams still rely on the AN system with all its inherent flaws. Pushlox is an extremely cost effective replacement for any fluid, pneumatic or gas connection. With insurance, maintenance and operating costs at an all time high, who can afford to have any connection come loose. Pushlox has 24 improved features, all very apparent upon inspection of the design. The Pushlox Locking fittings come, and are installed as a unit. No assembly is required. These feature makes this product very user friendly.

Where on a todays high performance vehicles or machines, is the utilization of some form of torque retention not used on anywhere except the plumbing systems? You have lock nuts, safety wire or Loctite™ not to mention excessive amounts of torque used to keep all your fasteners from causing catastrophic failure.
At today's speeds who can afford to run through someone else's oil, water, power steering fluid or fuel that has been laid down on the racetrack. For years racing teams have competed without the latest safety systems, but now the major sanctioning organizations of motors sports have made it mandatory to use:
