<DIV><FONT size=2 face=Arial>The cross section that's called for should work
well. As I said in the earlier E-mail, it's pretty important to have the
mating surfaces true to each other. Weld first then machine. That
will keep all surfaces true and give you the proper compression of the O-ring
all the way around the hatch.</FONT></DIV>

O-rings</DIV>
<DIV><BR></DIV>
<DIV>Hi Dan:</DIV>
<DIV> </DIV>
<DIV>Sorry for the confusion, a run on sentence will do that. I was
asking about the size/cross-section of the O-ring. The 316 stainless steel
ring would be welded to the dish lid in which the O-ring would be mounted
using a machined dove-tail grove, </DIV>
<DIV> </DIV>
<DIV>Thanks for the input.</DIV>
<DIV> </DIV>

<PERSONAL_SUBMERSIBLES@PSUBS.ORG><BR><BR>> John,<BR>> <BR>> Are you
sure you really want an O-ring with a one inch cross <BR>>
section??????????You'd need to machine a groove just under an <BR>> inch
deep and an inch in across to accept it. If your hatch <BR>> cover is what
the print calls for, it's not think enough for a <BR>> groove of that size.
<BR>> <BR>> The .275 cross section is plenty. The two mating surfaces
being <BR>> flat and mating with no gap is much more important then the
O-<BR>> ring cross section. <BR>> <BR>> You should be fine with the
O-ring called for. <BR>> <BR>> Dan H.<BR>> ----- Original Message

O-rings<BR>> <BR>> <BR>> Hi All:<BR>> <BR>> I need O-rings for
the entry hatches which are 24" id. 26" od. <BR>> he question I have is,
what is the best cross section size to <BR>> use The parker site has the
E1157 @ .275 it seemed a little <BR>> small to me. I have not yet machined
the dove -tail grove yet. <BR>> Also are there any specs. available for
setting up a 3 dog <BR>> mechanism, able to open from inside or out?
<BR>> <BR>> Looking forward to the convention.<BR>> <BR>> <BR>>
