Astracast Shannon Twin Lever TP0420 O Ring Kit 1425R & Grub Screw

• We have seen several versions of this tap with different spare parts.
• The genuine part detailed below will not fit any other Shannon Tap.
• We have also observed that customers who might have an invoice with this code TP0420  on their paperwork have in fact have a different Tap.
• So we would advise that you check your own tap visually (see visual clues below) and also remove the spout and compare it to the images below too.  This is to save you ordering the wrong (incompatible) part.

Astracast Shannon Twin Lever TP0420 Handles – Pop Off Indicators Clue :

Your own handles should look like this picture below.  If your own handles do not have these indicators shown then the 14245R O Ring Kit is not the part here for your Tap and we do not stock it.

Astracast Shannon Twin Lever TP0420 Spout Detail showing O Ring Kit :  

Depending on when your own Tap was produced you might or might not have the smaller white O Ring.  This is not an issue. You will just replace like for like.  Just ensure that your own o rings look like either spout below.

Astracast Shannon Twin Lever TP0420 Valve clue :

San Marco or SMR will be stamped on your own valve.  Here is the Valve in more detail.

• We always recommend that you should check your own Spout before ordering a new set of O Rings.
• The reason for doing this is because if you have a pinhole in your spout (see example below of a pinhole) then replacing the O Ring Kit will not fix this.
• If you have a pinhole you will need to replace the entire Spout'
• Here is our Guide : How to remove Kitchen Tap Spout so that you can check for pinholes.
• If you think that you have a pinhole, and do not know what Spout you need, then contact us us with the details of your Tap e.g a picture, together with any other information that you know e.g the Brand might be marked on the Tap, so that we can send you a link to the correct Spout that you require.
• Here is the example of a pinhole in a Spout.

Tip when changing the O Ring Kit :

• Usually only the black O Rings need to be replaced on your Spout unless one of the white O rings is broken.
• Some White O Rings have an intentional split in them as they might be used in some spouts that require a grub screw so an intentional split in the ring does not mean it is broken.
• Your new O Ring Kit might have surplus O Rings that may not be required for your particular Spout as some O Ring Kits had an additional smaller ring added in later years for stability.
• You can add Plumbers Grease to aid the movement or washing up liquid. Do not use anything like vaseline that will cause rubber to perish.
