# 777软管 - 4000 PSI 恒定工作压力 > 派克777软管的外径（O.D.）更小，重量更轻，而且比其他4，000psi的软管更加柔软。软管的组装和安装更加便捷，减轻操作人员的工作强度。 所属技术：流体连接 ## 系列介绍 派克4,000 psi恒定工作压力的777软管，在不牺牲性能的前提下提供了巨大的优势。257°F的额定温度的软管符合ISO 18752 CC性能要求，并且适配43系列接头，这种软管/接头的组合可为您提供数百种接头选择，以满足各种应用和布管挑战。派克777软管有标准、耐磨和超耐磨三种外层可供选择，可用于多种行业和应用。外径的减小使软管易于在紧凑的建筑机械中布管。重量的减轻对垃圾车极为有利，因为车辆重量决定其额定载重。更大的柔软性使软管在安装过程中更易布管，在铰接处的表现也更好。市场：• 农机 • 建筑机械 • 林业 • 采矿 • 垃圾车 特点/优势：• 更小的外径（O.D.） • 重量比其他4,000 psi的软管更轻• 更大的柔软性意味着更易安装 • 符合ISO 18752 CC标准 • 额定温度达257°F • 与43系列接头兼容 • 弯曲半径不到SAE标准的一半 • 标准、耐磨和超耐磨三种外层可供选择 应用：• 石油基液压油和润滑油 ## 技术参数 | 参数 | 值 | 单位 | | --- | --- | --- | | 最低运行温度 | -40 °F, -40 °C | | | 介质 | Lubricants (Oils), Petroleum Hydraulic Fluids (Petroleum Base) | | | 符合规格 | ISO 18752, MSHA TC, ST & CP covers only | | | 兼容配件 | 43 Series | | | 重量 | 0.40 to 0.99 kg/ft, 0.60 to 1.47 kg/m, 0.40 to 0.99 lb/ft | | | 内径 | 3/8 to 1 inch, 3/8 to 1 inch, 10 to 25 mm, 10 to 25 mm | | | 最高运行温度 | 100 to 125 °C, 212 to 257 °F | | | 应用 | Agriculture Equipment, Construction Equipment, Forestry, Mining, Refuse | | | 软管加固材料 | 4 Spirals of Steel Wire | | | 最小弯曲半径 | 2.5 to 4.75 inch, 50 to 120 mm | | | 外径 | 0.78 to 1.38 inch, 0.78 to 1.38 inch, 19.9 to 35.0 mm, 28.4 to 35.0 mm | | | 最大运行压力 | 4000 psi, 28 bar | | | 软管内管材料 | Synthetic Rubber | | ## 型号入口（首批） - [777-12](https://hypher.com.cn/products/model/777-12-11123c720990a688/index.md) - [777TC-12](https://hypher.com.cn/products/model/777tc-12-f8b9cc989173f3b8/index.md) - [777ST-12](https://hypher.com.cn/products/model/777st-12-1861ade67b191184/index.md) - [777-16](https://hypher.com.cn/products/model/777-16-2694257155252c3c/index.md) - [777TC-16](https://hypher.com.cn/products/model/777tc-16-57fef074c7ed8e22/index.md) - [777ST-16](https://hypher.com.cn/products/model/777st-16-82e5f4d8a76ece48/index.md) - [777-10](https://hypher.com.cn/products/model/777-10-8b499d2f4caeeba1/index.md) - [777-6](https://hypher.com.cn/products/model/777-6-0b71461cacfc5373/index.md) - [777-8](https://hypher.com.cn/products/model/777-8-5d4206ebcc0ac9b8/index.md) - [777ST-10](https://hypher.com.cn/products/model/777st-10-2082fa9ce6aecf55/index.md) - [777ST-6](https://hypher.com.cn/products/model/777st-6-b925e45ffca35497/index.md) - [777ST-8](https://hypher.com.cn/products/model/777st-8-75e65367d901106a/index.md) - [777TC-10](https://hypher.com.cn/products/model/777tc-10-43ac6a33d2870328/index.md) - [777TC-6](https://hypher.com.cn/products/model/777tc-6-029a4a769ff1dac8/index.md) - [777TC-8](https://hypher.com.cn/products/model/777tc-8-1d3fbf1226b630d6/index.md) - [777CP-12](https://hypher.com.cn/products/model/777cp-12-5b2eb4d3dc799990/index.md) - [777CP-16](https://hypher.com.cn/products/model/777cp-16-e92e0a6ec29a9666/index.md) - [777CP-8](https://hypher.com.cn/products/model/777cp-8-cfc8a583a6ff7db5/index.md) - [777CP-6](https://hypher.com.cn/products/model/777cp-6-643223c5faaed355/index.md) ## 技术资料与 CAD - [ABS Type Approval Cert 777 Hose](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Websphere-Supporting-Literature/ABS%20Type%20Approval%20Cert_777%20Hose.pdf)：document - [Critical Protection (CP) Hose Cover](https://www.parker.com/content/dam/videos/fcg/hose-products-division/HPD_CP-Hose-Cover-Video.mp4)：document - [DNV Type Approval Cert 777 Hose](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Websphere-Supporting-Literature/DNV%20Type%20Approval%20Cert_777%20Hose.pdf)：document - [FCG HPD 777 Hose Bulletin- 4480-B208](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Websphere-Supporting-Literature/FCG_HPD-BUL-B208_777_Hose.pdf)：document - [FCG HPD Critical Protection Hose Cover](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Websphere-Supporting-Literature/FCG_HPD-Critical-Protection-Hose-Cover-BUL-4480-B219.pdf)：document - [GlobalCore Bulletin](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Parker_GlobalCore_Brochure.pdf)：document - [Lloyd's Register Type Approval Cert 777 Hose](https://www.parker.com/content/dam/Parker-com/Literature/Hose-Products-Division/Websphere-Supporting-Literature/Lloyd's%20Register%20Type%20Approval%20Cert_777%20Hose.pdf)：document - [New GlobalCore Video - 2025](https://www.parker.com/content/dam/videos/fcg/hose-products-division/HPD_Parker-GlobalCore-Hose-Overview.mp4)：document 资料来源：[原始系列资料](https://ph.parker.com/cn/zh/product-list/4-000-psi-constant-working-pressure-777-hose) 价格、库存和交期请联系上海海费确认。更多型号和资料见 [完整系列页面](https://hypher.com.cn/products/fluid-connectors/4-000-psi-constant-working-pressure-777-hose)；[联系技术支持](https://hypher.com.cn/contact)
