Crafted from heavy-duty, chemical-grade PPH (Polypropylene Homopolymer), these S5-rated end caps are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperature loads ranging from -20°C to 100°C.\n\u003c\/p\u003e\n\u003cp\u003e\n  Designed to be welded together into a single, integrated molecular piping system, this non-toxic and robust series is highly suitable for terminating pipeline runs in acid pickling loops, electroplating lines, waste acid recovery, wastewater treatment, and chemical processing networks.\n\u003c\/p\u003e\n\n\u003ch3\u003eSuperior Chemical Stability \u0026amp; Material Resilience\u003c\/h3\u003e\n\u003cp\u003e\n  PPH (Polypropylene Homopolymer) is widely preferred in heavy chemical processing and environmental protection fields due to its exceptional resistance to chemical corrosion, acids, alkalis, and abrasive wear. These end caps are widely deployed to seal water lines, power plant cooling conduits, and food processing lines. They are completely non-toxic and odorless, maintaining high security and water purity throughout the entire system.\n\u003c\/p\u003e\n\n\u003ch3\u003ePrecision Socket Fusion for a Seamless Molecular Bond\u003c\/h3\u003e\n\u003cp\u003e\n  These cap fittings feature a socket-type internal cavity designed to slide over standard PPH pipes.

Use a standard socket fusion hot-melt welding machine equipped with matching heating adaptors to heat both ends simultaneously. Once heated to the target temperature, quickly push the pipe into the socket depth (I) without twisting, and hold it firmly until the molecular bond solidifies.\u003c\/p\u003e\n\n\u003c!-- Recommended System Bundles \u0026 Cross-Linking (Strictly 3 Links, Chinese placeholders inside href) --\u003e\n\u003cdiv style=\"background-color: #fcfcfc; border: 1px solid #e5e5e5; padding: 15px; border-radius: 6px; margin-top: 30px;\"\u003e\n  \u003cp style=\"margin: 0 0 10px 0; font-size: 15px; font-weight: bold; color: #333;\"\u003eRecommended System Bundles \u0026amp; Companion Products:\u003c\/p\u003e\n  \u003cul style=\"margin: 0; padding-left: 20px; font-size: 14px; color: #555;\"\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Hot-Melt Pipeline Valves \u0026amp; Flanges:\u003c\/strong\u003e To integrate heavy-duty control ball valves or flanges, explore our matching \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pph-hot-melt-fittings\/products\/chemical-grade-pph-butt-fusion-pipe-fittings-valves-s5-1-25mpa-hot-melt-weld-union-flange-tee-elbow-ball-valve-20mm-110mm-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eChemical-Grade PPH Butt Fusion Pipe Fittings \u0026amp; Valves\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Threaded Branch Transitions:\u003c\/strong\u003e Connect these rigid lines directly to standard G-threads using our matching \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pph-hot-melt-fittings\/products\/chemical-grade-pph-female-threaded-tee-elbow-hot-melt-socket-fusion-s5-1-25mpa-pipeline-fitting-20mm-63mm-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003ePPH Female Threaded Tees \u0026amp; Elbows\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 0;\"\u003e\n      \u003cstrong\u003eFor Diameter Reduction:\u003c\/strong\u003e Transition G-threaded outlets down to smaller internal thread sizes using our \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/misc-adapters-transition-fittings\/products\/pvc-internal-and-external-thread-repair-insert-g-pt-bsp-male-to-female-reducing-bushing-pipe-fitting-1-2-to-2-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003ePVC Male-to-Female Reducing Bushings\u003c\/a\u003e.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Atradesen","offers":[{"title":"20mm (DN15)","offer_id":56827403239590,"sku":null,"price":0.52,"currency_code":"USD","in_stock":true},{"title":"25mm (DN20)","offer_id":56827403272358,"sku":null,"price":0.63,"currency_code":"USD","in_stock":true},{"title":"32mm (DN25)","offer_id":56827403305126,"sku":null,"price":0.72,"currency_code":"USD","in_stock":true},{"title":"40mm (DN32)","offer_id":56827403337894,"sku":null,"price":0.98,"currency_code":"USD","in_stock":true},{"title":"50mm (DN40)","offer_id":56827403370662,"sku":null,"price":1.36,"currency_code":"USD","in_stock":true},{"title":"63mm (DN50)","offer_id":56827403403430,"sku":null,"price":3.45,"currency_code":"USD","in_stock":true},{"title":"75mm (DN65)","offer_id":56827403436198,"sku":null,"price":3.98,"currency_code":"USD","in_stock":true},{"title":"90mm (DN80)","offer_id":56827403468966,"sku":null,"price":5.87,"currency_code":"USD","in_stock":true},{"title":"110mm (DN100)","offer_id":56827403501734,"sku":null,"price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2588\/6118\/files\/Chemical-Grade_PPH_Socket_Fusion_End_Cap_S5_1.25MPa_Hot-Melt_Pipe_Cap_Plug_Seal_Cover_Fitting_20mm_-_110mm_-_Atradesen-003.png?v=1784344246","url":"https:\/\/atradesen.com\/products\/chemical-grade-pph-socket-fusion-end-cap-s5-1-25mpa-hot-melt-pipe-cap-plug-seal-cover-fitting-20mm-110mm-atradesen","provider":"Atradesen","version":"1.0","type":"link"}
