It suits water filter installs, under-sink drinking water setups and other water lines where two different tube sizes need to meet in a straight run. As a universal fitting rather than a brand-specific spare, it is not tied to any particular appliance model, so match it by tube size instead of by brand.\u003c\/p\u003e\n\u003ch2\u003eJoining 3\/8 and 5\/16 inch water tube with a straight reducer\u003c\/h2\u003e\n\u003cp\u003eWater filter kits and fridge water lines are not always plumbed with one tube size from end to end. A filter housing might take 3\/8 inch tube while the line running on to a tap or appliance is 5\/16 inch, or the other way round. A straight reducer bridges that change in size without adding a bend. Replace an old connector if it weeps at either end, if the tube keeps pulling free, or if the body is cracked or discoloured. A slow drip at a fitting can ruin cabinets and flooring long before anyone spots it.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGeneric part number 431-516\u003c\/li\u003e\n\u003cli\u003eStraight reducer between 3\/8 inch and 5\/16 inch tube\u003c\/li\u003e\n\u003cli\u003eSuits water filter and drinking water tube runs\u003c\/li\u003e\n\u003cli\u003eUniversal fitting, not specific to one appliance brand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eTube size, one end\u003c\/th\u003e\n\u003ctd\u003e3\/8 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTube size, other end\u003c\/th\u003e\n\u003ctd\u003e5\/16 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eStraight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eFitting the reducer\u003c\/h2\u003e\n\u003cp\u003eTurn off the water supply and open a tap further down the line to release the pressure before you cut or remove any tube. Measure the outside diameter of both tubes so you know which end takes which size. Cut each tube end square and clean with a proper tube cutter, make sure each one is fully seated in the fitting, then restore the water and watch the joint for a few minutes.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eHow do I know if my tube is 3\/8 or 5\/16 inch?\u003c\/h3\u003e\u003cp\u003eMeasure the outside diameter of the tube with a vernier or a fine ruler. 3\/8 inch tube is about 9.5mm across and 5\/16 inch tube is about 7.9mm.
