I read in a post that a 13xx valve is the same as a 362 valve but after removing the trigger on my 362 and my Driter/2289 i see the front trigger screw on the 362 threads into the pump tube only and the Drifter front trigger screw threads into the valve . Has anyone here put a 13xx valve in a 362 I like the way the 13xx threads into the valve better .

The 362 valves should be the same as the 13xx guns.
The front trigger frame 8-32 screw threads into the valve.
That's how my 362 was assembled.
Last month I ordered three 760 front valve sections, p/n 417-034.
It's the same p/n that the 362 shows in their IPB.
I received valves that had a cut out similar to the PCP guns.
Crosman sent me the correct valves but left me wondering what was going on.
Perhaps the late model 362 is attaching the trigger frame as you describe.
You should be able to put a 13xx valve in the 362.
What is the s/n and when did you receive your 362?
Do you know the thread size of the screw?

I have put a 13xx flat top valve in a c362 no problem ;)
-
I do not have the 362 with me right now but i got it last week from PA when i took the trigger off and saw how short it was i got out my light and looked the tube is threaded and the valve has a grove around it . I had also bought a c2023 the valve on it is threaded so i was surprised to find the 362 not threaded. I would prefer it to be threaded but guess it does not really matter . Actually i liked the c2023 so much that i wanted to get a 362 to mod . I sold the c2023 and bought a 362 so i could mod it.

Yepper there different but no big deal i guess.

I got it a couple weeks ago from PA

Very curious. I wonder why? My 362 has the threaded valve as do the original valves from my other 13xx guns. I thought the idea behind the threaded valve was to help prevent it from pushing backwards.
It looks like the channel is in the same location as where the threads would be so as long as the trigger frame screw size hasn't changed, a threaded valve should align correctly using a little longer screw?
-
one operation for the groove... 2 for the drilled and tapped screw hole...
-
But now they have to drill & tap the tube.
-
I can see the grooved valve being more idiot proof though during assembly. Drill and tap the valve wrong and the TP is misaligned. Of course now they have to rely on only the TP and its seals to keep everything aligned. Not that it should rotate out of alignment ….. BUT
-
The rear section of the valve where the TP is, is only held in place by the TP and the rear tube flange anyway. It provides the ability to adjust the rear section slightly in order to get a perfect alignment with the TP. For those who pin the valve in the rear, they still can but as you say, if they drill and tap incorrectly, alignment is off. This groove prevents those who drill and tap for front valve pinning. Something that many do either by itself or in combination with a rear valve pin. I did not pin the valve in my 362 after a Crosman engineer told me that after all the pump testing they did, the valve showed no signs of backward movement, but it is a problem reported by many in other 13xx platforms. The groove doesn't make sense to me, but Crosman has their reasons for it I suppose?
A longer screw for the front trigger frame would help hold the valve in the front from allowing the valve slipping back, but not to the degree that drilling and tapping would. I suppose one could always make a filler block shaped to fit the groove, then drill and tap that?

Robert, good point. And I have done that. There have also been many times I’ve tried different ways to reduce headspace, from adjustable pumps, to shims. Remember stuffing pistons? With the grooved valve, it might be easier to fine tune any pump head space issues, when modding.

I never stuffed one myself. Never had a stock one in long enough, before switching to FTP, to try it, lol. The curious part for me is... They are not saving any money by adding the groove, and the groove behind the o-ring would not have much effect, if any, forward of it? The only advantage I can see with this is now you can align the rear to the TP, and screw out the front slightly, which like you say, would help with headspace issues but only to the point where it doesn't properly seal at the center. Even stranger is that Dan's 362 is a very early serial number (127) where mine is 806, assuming of course he is talking about the original 362 and not the anniversary edition. No one else has found this in their 362's, not that anyone has mentioned anyway.

That is the valve out of the 362 i never removed the valve from the c2023 Anniversary one but i did change the trigger bolts to stainless steel and it had the valve like 13xx have. I bought a 362 and a Drifter 2289 from Pyramyd air i like the 2289 more and have decided to do some mods on it mainly with parts i already have 1701P trigger etc.
