• Change inlet liners faster and more easily.
• Gas lines are attached to shell weldment bottom to help eliminate broken gas lines.
• Gas lines don’t interfere with routine maintenance.
• Weldment removal tool allows for quick removal of the hot weldment without
fingers ever touching hot surfaces.
• Weldment stays secure in the tool for reattachment.
The importance of injection port maintenance has been well documented by instru-
ment and column companies industry wide. Restek has made it easy to carry out this
maintenance with the innovation of our EZ Twist Top® injection port.
tech tip
Which EZ Twist Top® injection port should you buy?
The type of split vent trap you have connected to the EPC module/block on your 6890/6850
Agilent GC determines which EZ Twist Top® Injection Port you need to buy.
Simply remove the top and rear panel on the GC and see if you have the small (pencil type) split
vent filter (cat.# 22820) or the large canister type filter (cat.# 23031) attached to the split vent gas
line. If you have the small (pencil type) split vent filter, you need the EZ Twist Top® injection port
for Agilent 6890/6850 GCs (cat.# 22721 or 22722). If you have the large canister filter, you’ ll need
the EZ Twist Top® with optional split vent for Agilent 6890/6850 GCs, for use with large canister
type filters (cat.# 22735 or 22736).

Simply slip the weldment removal tool over
the weldment, then twist and remove the
weldment. For speed and efficiency, the
weldment stays secured in the weldment
removal tool until you reattach it.
