Description

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.
• This is important because if your spout has a pinhole (see example below), replacing the O-ring kit won't resolve the issue.
• 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 with details of your tap, such as a picture and any other information (e.g., brand markings), so we can send you a link to the correct spout.
• Here is the example of a pinhole in a Spout.

Tip when changing the O Ring Kit :

• Usually, only the black O-rings need replacing unless one of the white O-rings is damaged.
• Some white O-rings have an intentional split for use in spouts with a grub screw, so a split does not indicate it is broken.
• Your new O-ring kit may include extra rings not needed for your spout, as some kits were later updated with a smaller ring for added stability.
• Use plumber's grease or washing-up liquid to aid movement, but avoid vaseline as it can damage the rubber.
