Plumbers, contractors, and serious DIYers working with BSP-threaded systems need a reducing bushing that threads in cleanly, seals reliably, and holds up over years of service — whether it's behind a wall, under a sink, or in an outdoor irrigation line.\u003c\/p\u003e\n\u003cp\u003eEach piece is a one-body stainless steel BSP reducing bushing with a male (external) thread on the outside and a female (internal) thread on the inside, allowing you to step down from a larger pipe to a smaller one within the same BSP thread family. Available in 13 size combinations ranging from 1\/4\" to 2\" BSP, covering the most common reduction pairings used in residential and light commercial plumbing. Sizes follow standard BSP nominal designations — select the combination that matches your existing pipe threads.\u003c\/p\u003e\n\u003cp\u003eThese stainless steel BSP male-to-female reducing bushings are well suited for cold and hot water supply lines, compressed air systems, hydraulic circuits, and outdoor irrigation manifolds where corrosion resistance matters.

Wrap PTFE tape in the direction of the thread (clockwise when looking at the end of the male thread) for 2–3 layers. This is standard practice for BSP threaded pipe fittings in both water and gas applications.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat tools do I need to install a BSP reducing bushing?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eInstallation typically requires a pipe wrench or adjustable wrench sized to fit the hex body of the bushing. Apply PTFE tape to the male threads, hand-tighten first, then use a wrench to snug the fitting — generally 1–2 additional turns past hand-tight is sufficient for most water and air applications. Avoid over-tightening, which can stress the threads or crack adjacent fittings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003c!-- ⑥ CTA BAR --\u003e\n\u003cdiv class=\"hdiy-cta\"\u003e🛒 Select your \u003cstrong\u003esize (BSP) and quantity\u003c\/strong\u003e above, then add to cart — ships from our US warehouse.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"1\u00262\" to 3\u00264\" \/ 1 pcs","offer_id":52336718643474,"sku":"PENG026516x1","price":3.66,"currency_code":"USD","in_stock":true},{"title":"1\u00262\" to 1\u00264\" \/ 1 pcs","offer_id":52336718676242,"sku":"PENG026517x1","price":4.07,"currency_code":"USD","in_stock":true},{"title":"1\u00262\" to 3\u00268\" \/ 1 pcs","offer_id":52336718709010,"sku":"PENG026518x1","price":4.07,"currency_code":"USD","in_stock":true},{"title":"1\" to 1\u00262\" \/ 1 pcs","offer_id":52336718741778,"sku":"PENG026519x1","price":5.56,"currency_code":"USD","in_stock":true},{"title":"1\" to 3\u00264\" \/ 1 pcs","offer_id":52336718774546,"sku":"PENG026520x1","price":5.29,"currency_code":"USD","in_stock":true},{"title":"1-1\u00264\" to 1\u00262\" \/ 1 pcs","offer_id":52336718807314,"sku":"PENG026521x1","price":12.91,"currency_code":"USD","in_stock":true},{"title":"1-1\u00264\" to 3\u00264\" \/ 1 pcs","offer_id":52336718840082,"sku":"PENG026522x1","price":11.95,"currency_code":"USD","in_stock":true},{"title":"1-1\u00264\" to 1\" \/ 1 pcs","offer_id":52336718872850,"sku":"PENG026523x1","price":11.14,"currency_code":"USD","in_stock":true},{"title":"1-1\u00262\" to 1\u00262\" \/ 1 pcs","offer_id":52336718905618,"sku":"PENG026524x1","price":18.21,"currency_code":"USD","in_stock":true},{"title":"1-1\u00262\" to 3\u00264\" \/ 1 pcs","offer_id":52336718938386,"sku":"PENG026525x1","price":16.58,"currency_code":"USD","in_stock":true},{"title":"1-1\u00262\" to 1\" \/ 1 pcs","offer_id":52336718971154,"sku":"PENG026526x1","price":15.35,"currency_code":"USD","in_stock":true},{"title":"1-1\u00262\" to 1-1\u00264\" \/ 1 pcs","offer_id":52336719003922,"sku":"PENG026527x1","price":13.04,"currency_code":"USD","in_stock":true},{"title":"2\" to 1-1\u00262\" \/ 1 pcs","offer_id":52336719036690,"sku":"PENG026528x1","price":18.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture7of22_7e9bb808-f075-49f0-be71-afa5cfa5128d.jpg?v=1781154190","url":"https:\/\/homediyer.com\/products\/stainless-steel-bsp-reducing-bushing-male-female-thread-pipe-fitting","provider":"HomeDIYer","version":"1.0","type":"link"}
