核心特點與優勢 / Key Features & Advantages

1.1 Hi Cupla（標準型低壓氣動快速接頭）

Hi Cupla 系列是工廠氣動管路中最常用的經典快速接頭，適用於一般氣動工具及空壓機管線連接。

· 單向開閉閥門：母頭（Socket）內置自動開閉閥門，在公母頭分離時能瞬間切斷氣流，防止氣體洩漏與壓力驟降。

· 卓越的耐用性與抗衝擊性：針對鋼製主體進行了關鍵部位的特殊熱處理，硬度極高，具有極強的抗疲勞與抗磨損能力。

· 大流量設計：流體阻力極小，能提供超越同級接頭的氣流量，確保氣動設備獲得充足且穩定的動力。

· 多元化接口相容：支援螺紋型（PT/R/Rc）、竹節型（Hose barb）及螺帽型（Nut joint）等多種管路連接方式。

1.2 Hi Cupla BL（安全鎖型低壓氣動快速接頭）

Hi Cupla BL（Built-in Lock）在標準型的基礎上引入了物理鎖定機構，專為高流動性、高震動或高安全要求的作業環境設計。

· 內置式套筒鎖（Sleeve Lock）：當公母頭完成連接後，只需輕輕旋轉外層套筒，即可將接頭鎖定。

· 強效防意外脫落：在鎖定狀態下，即使接頭受到強烈的地面拖拽、重物擠壓或意外拉扯，套筒也無法向後滑動，確保接頭絕不分離。

· 震動防護密封：承襲日東（Nitto）卓越的 O-ring 密封工藝，在高頻震動的氣動工具（如氣動衝擊扳手）上使用，依然保持完美的零洩漏。

Nitto Pneumatic Quick Coupling Series

The Nitto Professional-Grade Pneumatic Quick Coupling Series is specifically engineered for industrial high-pressure pneumatic systems, factory automation, pneumatic tools, and conventional air lines.

Technical Specifications

Item	Hi Cupla (Standard Type)	Hi Cupla BL (Safety Lock Type)

Technical Positioning	Industrial-grade general-purpose quick coupling (most common).	High-security, specialized coupling designed to prevent accidental disconnection.
Sleeve Locking Mechanism	None (unlocks via single-handed push-pull sleeve action).	Equipped (sleeve can be securely locked manually by rotating it after connection).
Safety Protection	When dragging hoses or impacting the ground, external forces may cause the sleeve to retract, risking accidental pipeline blowouts.	Once locked, the sleeve cannot retract, 100% eliminating the risk of accidental disconnection and whipping hoses causing injuries.
Body Material Options	Carbon Steel (Chrome-plated), Stainless Steel (SUS304), Brass.	Carbon Steel (Chrome-plated), Stainless Steel (SUS304) (No Brass version available).
Max. Working Pressure	• Steel / Stainless Steel: 1.5 MPa (15 kgf/cm²)• Brass: 1.0 MPa (10 kgf/cm²)	Steel / Stainless Steel: 1.5 MPa (15 kgf/cm²)
Proof Pressure	• Steel / Stainless Steel: 2.0 MPa• Brass: 1.5 MPa	Steel / Stainless Steel: 2.0 MPa
Applicable Fluids	Air (all materials), Water (Stainless Steel and Brass only).	Air (all materials), Water (Stainless Steel only).
Standard Seals / Temperature	Nitrile Rubber (NBR): -20°C to +80°C (Fluoro rubber / FKM can be custom-ordered for -20°C to +180°C).	Nitrile Rubber (NBR): -20°C to +80°C (The SN-BL Nut Lock Type is rated for -20°C to +60°C).
Interchangeability	Fully interchangeable. Standard sockets and BL-type sockets can both fit the same standard plug (male end).	—

Item	Hi Cupla (Standard Type)	Hi Cupla BL (Safety Lock Type)
End Connection Configurations	SM, SF, SH, SN, PM, PF, PH, PN	SM-BL, SF-BL, SH-BL, SN-BL (Socket end only)
Best Application Scenarios	Fixed workstations on production lines, general pneumatic tools, and air supply manifolds where equipment is stationary and free from dragging risks.	Shipyards, construction sites, heavy industrial assembly lines, and mobile operations requiring hoses to be dragged long distances across the ground.

Key Features & Advantages

1.1 Hi Cupla (Standard Low-Pressure Pneumatic Quick Coupling)

The Hi Cupla series is the most widely adopted, classic quick coupling across factory pneumatic pipelines, ideally suited for connecting general pneumatic tools and air compressor lines.

· One-Way Shut-Off Valve: The socket features a built-in automatic shut-off valve that instantly stops airflow upon disconnection, preventing gas leakage and sudden pressure drops.

· Excellent Durability & Impact Resistance: Key components of the steel body undergo specialized heat treatment to achieve extreme hardness, providing outstanding resistance to fatigue and wear.

· Large Flow Design: Engineered with minimal fluid resistance to deliver an airflow rate that outperforms competitor couplings in its class, ensuring sufficient and stable power for pneumatic equipment.

· Versatile Interface Compatibility: Supports a wide range of pipeline connection styles, including threaded (PT/R/Rc), hose barb, and nut joints.

1.2 Hi Cupla BL (Safety Lock Type Low-Pressure Pneumatic Quick Coupling)

Built upon the standard version, the Hi Cupla BL (Built-in Lock) introduces a physical locking mechanism tailored for high-mobility, high-vibration, or safety-critical work environments.

· Built-In Sleeve Lock: Once the plug and socket are connected, simply rotate the outer sleeve slightly to lock the coupling securely into place.

· Powerful Prevention of Accidental Disconnection: In its locked state, the sleeve cannot slide backward—even when subjected to harsh dragging across the floor, heavy crushing, or unexpected pulling—ensuring the coupling never separates under load.

· Vibration-Proof Sealing: Inheriting Nitto’s premier O-ring sealing technology, it maintains a perfect, zero-leakage performance even when mounted on high-frequency vibrating pneumatic tools (such as pneumatic impact wrenches).
