RTV/FIP Syringe Changes

Notification of change of syringe format affecting silicone based conductive adhesive and form in place materials supplied in 10ml 30ml and 55ml syringes

Up until the present time we have been supplying all our dispensable silicone materials in syringes from Nordson EFD.

These syringes were branded as Ultra and are the industry standard format with several other companies producing/suppling very similar (pattern) parts.

EFD Nordson have recently redesigned these parts, now badged as Optimum, with the usual claims of im-proved performance. Unfortunately, they have decided to make the original Ultra parts obsolete. In order to maintain the existing format, we tested the alternative parts that would still be available but none of these were found to be of suitable quality. This means that we have no choice other than to switch over to the new EFD Optimum format.

Generally, the basic size/format of the new Optimum syringe remains very similar to that of the Ultra type it replaces. The length and diameter of the syringes are the same and they still use the same luer-lock threaded twist feature for attaching dispense tips. Therefore, the new syringes should still fit onto dispense equipment that were running the original/current syringe types.

The main change is that the geometry of the piston head and nose of the syringes have been modified and are now elongated conical as shown in the attached photos. Also, the lugs at the base of the syringe have been redesigned and now require a new adaptor head if being used with pneumatic dispense equipment. This is main alteration that will affect any customers dispensing pneumatically as they will now require new adaptors.

Please note – these changes should not affect customers that use 10ml and 30 ml with plungers for dis-pensing by hand.

The Nordson EFD part numbers for the new adaptor headed that work with the new Optimum syringes (only required if dispensing pneumatically) are as follows:–

  • For the 10ml syringes – Nordson EFD part no. 7012339 ADAPTER ASM O 10CC BL
  • For both 30ml and 55ml syringes – Nordson EFD part no. 7012338 ADAPTER ASM O 30/55CC BL

We will need to swap over to the new format over the next few weeks. The exact timescale is a little un-certain as it depends on outgoing orders of existing stock.

We’re sorry for any inconvenience or disruption this may cause but we explored every possible alternative to avoid making this change.
