Overview

SAF-AIR push type fuel drain valves are close tolerance valves of simple design. These valves provide the most trouble free operation of any other line of valves in the industry. SAF-AIR valves are manufactured with an o-ring placed on the stem to seal against a flat seat on the body. This design eliminates an area where dirt can gather, thus putting an end to the main cause of fuel drain valve drip. FAA & PMA APPROVED.

Note: Aircraft applications are for general reference only. Verify correct valve for your aircraft before ordering.

I purchased this drain valve in case I encounter a leaking drain valve while away from home - its MUCH easier to replace the whole valve than trying to fiddle with replacing just the o-ring.

SAF-AIR DRAIN VALVES CAV-110

These are standard on the Vans RV-8 and I carry a spare with me at all times. I have found that the O-Ring will fail from time to time and having these ready to quickly swap allows me to minimize fuel spilling. Then I replace the MS29513-006 O-Ring on the valve I just removed and I have a spare ready to go for the next time.

Have used this drain before,and after around 10 years the seal has warn-out and needed replacement. I am happy with how this fuel drain has preformed.

Perfect replacement. Just seemed better to change to valve than the O-ring considering they are 20+ years old. I saved an old one as an emergency part.

SAF-AIR DRAIN VALVES CAV-110

October 14, 2021

Purchased to replace original valve on gascolator that constantly leaked. So far, this one is leak free (but has less than 1 hour on the Hobbs, so ...)

Gwen W

These are good valves however, after a number of years, the o-rings begin to leak. They are relatively easy to replace, if you can find new ones. These valves use -006 Viton o-rings, which are hard to find. The smallest Viton 0-rings that A/C Spruce sells are -008, which are too large.

David S

I have 7 of these valves installed in my aircraft. Every single one of them has failed in the three years the aircraft has been flying. I consider t his to be the least reliable piece of equipment on the airplane (by a wide margin). The steel shaft corrodes if its anywhere near the exhaust gas flow. It corrodes if any moisture is present. The o-rings sometimes stick against the valve seat and roll causing them to split (and leak) the next time one attempts to drain fuel. In short, this valve is a substandard part and a giant pain in the backside. Spend the extra money to buy the Andair DV-125 (for 1/8 NPT threads) - its stainless, comes with a Viton 0-ring and never seems to fail. It costs more but is a far, far superior product.

Q: What is the correct replacement O-ring for the CAV-110 drain valve?

It only needs the tip o-ring, part # MS29513-006.

Q: Does the CAV-110 have a wire hole so it can be safety wired? I do not see it in the photo.

No. The CAV-110 (05-01865) does not have a wire hole drilled into it for safety wire.

Q: What size socket wrench to remove/replace? Our current leaky valve requires 5/8

This would use a 1/2" socket.

Q: What hose fitting can I use to connect the CAV-110 to a 1/4 ID fuel hose? I would like a 45 degree one if possible. It would have to be a female (to receive the CAV-110) with a hose or barb to go into the fuel line.

You would need an an844-4 (steel) or -4d(alum) and an AN910-1(brass) of -1D(alum coupling.
