The push-in collet grips the tube OD and the internal O-ring seals the bore, providing a tool-free, leak-proof connection that can be released by pressing the release collar. The heavy-duty construction (reinforced collet and high-durometer O-ring) provides reliable sealing in industrial environments with vibration, pressure cycling, and temperature variation.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e PV (90° elbow union, push-to-connect both ends)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD:\u003c\/strong\u003e 4mm, 6mm, 8mm, 10mm, 12mm (select above)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e POM acetal or PA66 nylon (heavy-duty grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal:\u003c\/strong\u003e High-durometer O-ring + reinforced collet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Pressure:\u003c\/strong\u003e 0–1.0 MPa (0–145 PSI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range:\u003c\/strong\u003e 0°C to +60°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e Compressed air, water, light non-corrosive fluids\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 10 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePV Elbow vs PU Straight vs PE Tee\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePU (straight union):\u003c\/strong\u003e Joins two tubes inline.

For tighter bends, use a PV elbow fitting — attempting to bend below the minimum radius kinks the tube, restricting airflow and creating a stress point that will eventually crack.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I use PV elbow fittings for water circuits?\"\u003c\/em\u003e — Yes, for clean water and light non-corrosive fluids at pressures up to 1.0 MPa. Not suitable for hot water above 60°C, hydraulic oil, or aggressive chemicals.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"How do I release the tube from a PV elbow fitting?\"\u003c\/em\u003e — Press the release collar (blue or grey ring) firmly inward toward the fitting body while simultaneously pulling the tube straight out. On elbow fittings, pull the tube along its own axis — not toward the other port. Do not pull at an angle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCylinder port connections:\u003c\/strong\u003e 90° exit from cylinder ports in tight installations where straight fittings would require excessive clearance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel penetrations:\u003c\/strong\u003e Routing tubes through panels at 90° without a bend radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact automation:\u003c\/strong\u003e Direction changes in tight pneumatic circuits on small machines and robots\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAquariums \u0026amp; hydroponics:\u003c\/strong\u003e Air line direction changes in compact sump and filter installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e10 pieces — PV 90° elbow push-to-connect fittings in the tube OD selected above.\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"PV-4 \/ 10 PCS","offer_id":47850667311349,"sku":"14:201441572#PV-4;183:202360806#10 PCS","price":25.69,"currency_code":"USD","in_stock":true},{"title":"PV-4 \/ 50 PCS","offer_id":47850667344117,"sku":"14:201441572#PV-4;183:202360807#50 PCS","price":42.81,"currency_code":"USD","in_stock":true},{"title":"PV-6 \/ 10 PCS","offer_id":47850667376885,"sku":"14:10#PV-6;183:202360806#10 PCS","price":26.15,"currency_code":"USD","in_stock":true},{"title":"PV-6 \/ 50 PCS","offer_id":47850667409653,"sku":"14:10#PV-6;183:202360807#50 PCS","price":43.58,"currency_code":"USD","in_stock":true},{"title":"PV-8 \/ 10 PCS","offer_id":47850667442421,"sku":"14:173#PV-8;183:202360806#10 PCS","price":28.98,"currency_code":"USD","in_stock":true},{"title":"PV-8 \/ 50 PCS","offer_id":47850667475189,"sku":"14:173#PV-8;183:202360807#50 PCS","price":48.34,"currency_code":"USD","in_stock":true},{"title":"PV-10 \/ 10 PCS","offer_id":47850667180277,"sku":"14:193#PV-10;183:202360806#10 PCS","price":42.74,"currency_code":"USD","in_stock":true},{"title":"PV-10 \/ 50 PCS","offer_id":47850667213045,"sku":"14:193#PV-10;183:202360807#50 PCS","price":71.23,"currency_code":"USD","in_stock":true},{"title":"PV-12 \/ 10 PCS","offer_id":47850667245813,"sku":"14:350686#PV-12;183:202360806#10 PCS","price":52.68,"currency_code":"USD","in_stock":true},{"title":"PV-12 \/ 50 PCS","offer_id":47850667278581,"sku":"14:350686#PV-12;183:202360807#50 PCS","price":87.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/S4181000ef5554a708bb5f49088fdf310Q.webp?v=1773899437","url":"https:\/\/www.csldmcml.com\/products\/pv-elbow-pneumatic-quick-fitting-4-12mm-air-water-hose-push-connector-10pcs","provider":"Cable Parts Online","version":"1.0","type":"link"}
