{"product_id":"pump-replacement-tube","title":"Pump Replacement Tube","description":"\u003cp\u003eSeveral people have asked to replace the pump tube in their Pump Pen because the pump tube wore down, frayed, or got crusty. Whatever the reason - you can order replacement tubes for free - just pay the postage. \u003cbr\u003e\u003cbr\u003eYou should be aware that there is a ring that secures the pump tube inside the pen. Try to retain your ring when you remove the old tube. We don't yet have replacements for this part. We designed the pump tube so you don't really need the retaining ring, but it's a good thing to have. You can replace the tube, not use the ring, and still get good performance from the pump. We designed the mouth of the ink cartridge to press up against the tube and hold it securely in place. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e When we produce enough rings to sell them separately. we will charge a fee for them. In the meantime you can try a short section of drinking straw to hold the tube in place. \u003c\/p\u003e\n\u003cp\u003eWe suggest you order this product along with other items so you don't have to pay shipping for such a small part. This is especially true for customers outside the US where shipping costs more. \u003c\/p\u003e","brand":"Ackerman Pens","offers":[{"title":"Default Title","offer_id":49387633705182,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/ackermanpens.com\/fr\/products\/pump-replacement-tube","provider":"Ackerman Pens","version":"1.0","type":"link"}
