Similarly, virtually all metal connections expand as a system heats up, and then contracts as the system cools. Conventional worm gear, T-bolt, and other clamps are passive, in that expansion or contraction of components cannot be compensated for with out re-tightening or loosening the clamps. This clamping system is an active clamping mechanism, which monitors and then compensates for the changes by actually changing diameter through a unique worm gear Belleville assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHose I.D. - 4-1\/8 to 4-1\/2, Hose O.D. - 4.75 to 5.625\u003c\/li\u003e\n\u003cli id=\"isPasted\"\u003eRecommend max. torque - smaller id. sizes up to 730-3000 - 30 to 70 in.-lbs, larger id. sizes above 730-3000 - 50 to 120 in.-lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp id=\"isPasted\"\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBand  Housing: 304 Stainless Steel 5\/8 Wide Band\u003c\/li\u003e\n\u003cli\u003eBellville Spring Washers  Screw: 401 Stainless Steel\u003c\/li\u003e\n\u003c\/ul\u003e \u003c!--- cis2:m2lumZRk ---\u003e\n\u003cp\u003e\u003cstrong\u003eTrident Marine 730-4120 Stainless Steel Constant Torque Clamp\u003c\/strong\u003e is designed to provide reliable, consistent sealing for marine, automotive, industrial, and other demanding hose applications. Its 5\/8-inch-wide stainless steel band accommodates the specified hose size range while delivering dependable clamping force around the connection. The clamp is well suited for installations where temperature changes, vibration, and long-term hose compression can reduce the effectiveness of conventional clamping systems.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eMost rubber hose materials experience cold flow after installation, which can create torque loss and reduce sealing pressure. Metal connections can also expand as a system heats and contract as it cools. Unlike conventional worm gear, T-bolt, and other passive clamps, this active constant torque design helps compensate for these changes. Its unique worm gear and Belleville spring assembly monitors changes in the connection and adjusts the clamp diameter to help maintain more consistent pressure without requiring repeated manual tightening or loosening.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe clamp uses a 304 stainless steel band and housing for corrosion resistance and durable service in marine and other moisture-prone environments. The Belleville spring washers and screw are manufactured from 401 stainless steel, providing a robust clamping assembly for demanding installations. Recommended maximum torque varies by clamp size, ranging from 30 to 70 inch-pounds for smaller sizes and from 50 to 120 inch-pounds for larger sizes. Always follow the equipment manufacturer's installation requirements and use the appropriate torque for the application.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eTrident Marine part number 730-4120 is a practical choice when maintaining consistent hose sealing pressure is important. The constant torque mechanism helps reduce the need for maintenance caused by thermal cycling and hose material compression, supporting dependable performance in marine systems, engine compartments, plumbing connections, and other equipment using flexible hose.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eActive constant torque design compensates for hose compression and thermal expansion or contraction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e5\/8-inch-wide band supports secure clamping across the specified hose application range\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUnique worm gear and Belleville spring assembly helps maintain consistent sealing pressure\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e304 stainless steel band and housing provide corrosion resistance for marine and demanding environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e401 stainless steel Belleville spring washers and screw provide durable clamping performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecommended maximum torque ranges from 30 to 70 inch-pounds for smaller sizes and 50 to 120 inch-pounds for larger sizes\u003c\/li\u003e\u003c\/ul\u003e","brand":"Trident Marine","offers":[{"title":"Default Title","offer_id":44850077106218,"sku":"115307","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/115307XL.jpg?v=1789447108","url":"https:\/\/atticusgoods.com\/products\/trident-marine-730-4120-stainless-steel-constant-torque-hose-clamp-5-8-inch-band","provider":"Atticus Goods","version":"1.0","type":"link"}
