The 3\/8″ 3\/8″ x 1\/2″ Reducing Barrel Nipple<\/b>\u00a0is an essential “reducing” fitting designed to connect two female-threaded pipes or components of different diameters. Unlike “close nipples” which are threaded end-to-end, the barrel design includes a center section of unthreaded tube. This extra length provides better grip during installation and allows for precise spacing between components in complex plumbing manifolds.<\/p>\n Dual-Diameter Reduction:<\/b> Perfectly bridges 3\/8″ and 1\/2″ lines, eliminating the need for bulky multi-fitting adapters.<\/p>\n<\/li>\n Superior Material Quality:<\/b> Manufactured from 100% Genuine Brass<\/b> or Industrial-Grade Stainless Steel<\/b>, ensuring the fitting will not rust, flake, or contaminate potable water supplies.<\/p>\n<\/li>\n High-Pressure Reliability:<\/b> Rated for standard residential and commercial pressures up to 16 Bar (approx. 232 PSI)<\/b>, making it suitable for both municipal water lines and pumped filtration systems.<\/p>\n<\/li>\n Thermal Versatility:<\/b> Designed to operate safely in temperatures ranging from -20\u00b0C to 120\u00b0C<\/b>, ideal for hot water geysers and steam-based industrial processes.<\/p>\n<\/li>\n Standardized Threading:<\/b> Features precision-cut NPT or BSPT tapered threads to form a secure, water-tight seal when used with PTFE (Teflon) tape or pipe sealant.<\/p>\n<\/li>\n<\/ul>\n Water Purifier Installations:<\/b> Connecting 1\/2″ main water inlets to 3\/8″ feed lines for high-flow RO systems or under-sink filters.<\/p>\n<\/li>\n Sanitary Fittings:<\/b> Adapting bathroom shower valves, bidet sprays, and kitchen mixer taps where pipe sizes differ.<\/p>\n<\/li>\n Industrial Maintenance:<\/b> Used in chemical processing, air compressors, and pneumatic systems where 3\/8″ and 1\/2″ ports must be joined.<\/p>\n<\/li>\n Gas Line Transitions:<\/b> Suitable for low-pressure gas cooking equipment and industrial gas handling.<\/p>\n<\/li>\n<\/ul>\n Bridge disparate pipe sizes effortlessly with the 3\/8″ x 1\/2″ Reducing Barrel Nipple\u00a0<\/b>. This professional-grade connector features a short section of unthreaded pipe between two male threaded ends, allowing you to connect a 3\/8″ female fitting directly to a 1\/2″ female component. Whether you are upgrading household plumbing or maintaining industrial filtration units, this barrel nipple ensures a durable, leak-proof transition.<\/p>\n Size:<\/b> Reduces from 1\/2″ Male<\/b> to 3\/8″ Male<\/b> threads.<\/p>\n<\/li>\n Design:<\/b> “Barrel” style with a smooth unthreaded middle section for easier handling and specific spacing.<\/p>\n<\/li>\n Corrosion Resistant:<\/b> Available in high-quality Brass<\/b> or 304\/316 Stainless Steel<\/b> to withstand Sri Lanka\u2019s humid environment.<\/p>\n<\/li>\n Universal Use:<\/b> Compatible with water, air, oil, and gas pipelines.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"featured_media":9213,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[37,24],"product_tag":[],"class_list":["post-9211","product","type-product","status-publish","has-post-thumbnail","product_cat-ro-plant-accessories","product_cat-water-filters","desktop-align-center","tablet-align-center","mobile-align-center","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product\/9211","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/comments?post=9211"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media\/9213"}],"wp:attachment":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media?parent=9211"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_brand?post=9211"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_cat?post=9211"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_tag?post=9211"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Key Features & Benefits:<\/b><\/h3>\n
