O rings for a Crosman 1400 .22 rifle

[tj40]

I need O rings for an old Crosman 1400 made in the mid 70's ser #478038657.  This .22 rifle is like new but will not pump up and hold air, called Crosman and they no longer stock parts they gave me the phone number of a repair station and he wanted $60.00 plus freight and all it needs is new O rings.  If some one has parts please reply.  Tom Harris at ctharris@mmind.net

The valve in the 1400 only has 1 small o-ring on the check valve, and larger thin one between the valve body halves. The exhaust valve has whats called a quad seal. Its a flat ring seal with a slight groove in it. The quad seal is inside the exhaust valve cap, and seals around the valve nipple. Theres also a cup seal on the pump rod.
Are you sure the seals are the problem? If the sear isn't holding the valve cap closed the gun won't pump up. Check to be sure its adjusted right and isn't worn. Also, if the trigger spring is bent or weak, the sear may not engage.
If you aren't sure how to proceed with repairs on this gun, you may want to call here:

Ricks prices are about the best around, and his work is top notch. He's been doing Crosman repairs for almost 30 years. Also, he won't keep you waiting for months like some other well known places. Usually turn around is a couple weeks at most. The last gun I sent for a reseal cost $30 including shipping, and was back in 10 days.

Lots of the O-rings used in Air guns are pretty standard sizes. If you have the old ones no matter how worn you may be able to get replacements from a good motor spares shop or industrial hydraulic or pneumatic parts distributer. I dont know what its like in the U.S but here in england most of these palces have a trade counter and will serve the public. You could end up paying cents/pence for the replacements. Or do you have such a thing as "screwfix" there its a mail order firm where you can buy boxes of assorted o-rings and springs etc. I find them very usefull when repairing or modifying air guns. Good Luck. Hope this helps.
