ARF-A Gas Mask Drinking Connector Right Angle

This is an adapter to convert a commercially available potable water tube fitting into a right angle drinking tube connector for the French ANP-VP F1 / ARF-A or Polish MP-5 gas masks.  The commercial tube fitting is better than a fully 3D printed tube connector because it is properly rated for potable water and has a smooth polished finish for a better seal in the mask.  The standard drinking tube connector sticks straight out from the mask, so I thought a right angle option might be nice to reduce snag hazards. 

These masks are currently cheap on the surplus market, but most don't come with a drinking tube kit.  If you want one, buy this and get yourself a right angle stem to barb connector mentioned below and some tubing at the hardware store.  I recommend silicone tubing.  There are also "gas mask drinking tubes" that you can get on ebay which include a valve and may be adapted to your French/Polish gas mask using this part.

Additional Parts Needed:
This adapter has been tested with two variants of right angle stem to barb connectors by the fitting  manufacturer John Guest in 1/4" to 1/4" and 1/4" to 5/16" sizes.  I have found these parts here:

Recommended Improvement:
You can improve fluid flow by notching the tube fitting with a file or knife as shown in the photos.

I also have variants available in my shop profile for right angle and original fixed tube designs.

This is currently revision A, after initial testing with basic versatile plastic.  Clip sizes have been updated for better fitment.  Further updates may follow testing with multijet fusion.  Please contact me with any feedback you may have about fitment on your mask.
