All-Purpose Clean Break Series CN
Features:
The squirt-free clean break couplings of the CN series are mainly used in the chemical industry, for the loading and transport of fluids, e.g. at hose stations. Other application areas are also possible.
Due to the special design principle, a squirt-free connection and disconnection, even with long, filled hose lines under pressure up to 5 bar, is possible.
In case of limited space the handwheel can be dispensed with, due to the small operating force of the CN-025. A hook wrench can be used instead.
Key Benefits:
• clean break coupling with bayonet locking
• squirt-free operation
• connects under residual pressure
• small dimensions
• very good flow rates
Nominal Sizes:
25, 50, 80 and 100 mm
Media:
• water
• compressed air
• diverse fluids
• fuel
• lubricating greases / oils
• technical gases
Pressure Range:
up to 25 bar, depending on the nominal size

Parker’s Triple-Lok 37° flare tube fittings have been used in industry since Mr. Parker pioneered the product in the 1930s. The 37° flare fitting is the most popular industrial tube/hose fitting connection in the world.
Today, Parker offers a broad range of Triple-Lok fittings meeting SAE J514, ISO 8434-2 and military standards and specifications.
The Triple-Lok design is quite simple. The tube fitting consists of three pieces: the body, the nut and the sleeve. The tube end is flared at a mating 37° angle and sandwiched between the fitting nose (seat) and the sleeve creating an effective seal between the fitting nose and tube flare or hose.
Parker’s Triple-Lok fittings are manufactured in steel, 316 stainless steel and brass for optimum fluid compatibility and corrosion resistance. Furthermore, available sizes range from 1/8" tube O.D. to 2" tube O.D. in several configurations. Adaptability to global ports is another key benefit of Triple-Lok. (Standard ports include: SAE, straight thread ISO-6149, NPT, BSPT, BSPP and DIN.)
The Triple-Lok tube fitting is also readily available for metric tubing and hose adapter applications. Simply by changing the industry standard sleeve, the same Triple-Lok body can be adapted to metric tubing in sizes ranging from 6 mm tube O.D. to 38 mm tube O.D. Likewise, by using only the body without the nut and sleeve, the Triple-Lok fitting is used as an industry standard hose adapter.

Quick connect non-drip couplings designed solely for connecting low-pressure fluid and vacuum lines in which virtually zero spillage is critical.
CEJN non-drip couplings are adaptable to most applications and system requirements. The series includes two styles:
- Valved: One-hand operated; most commonly used style in fluid systems
- Valveless: Two hands needed for connection/disconnection; useful in coolant applications in which fluid loss at disconnection is not critical
Standard range includes three configurations: single shutoff, double shutoff, and straight through. The series is compatible with working pressures up to 290 PSI (20 bar) and temperatures up to 600° F (315° C) and is available in ¼-inch through 1-inch sizes. Constructions include nickel-plated brass with nitrile seals and AISI 316 stainless steel with Viton seals.
CEJN non-drip couplings are offered in four safety levels, enabling users to select the exact level of safety required. All levels are available with an optional safety-locking device that eliminates the risk of unintentional disconnection.

The dry break quick disconnect functions similar to a double shut-off quick disconnect however it provides a higher level of sealing during connection and disconnection. The dry break connects without leakage or fluid spray. Additionally, the design minimizes dead volume (the space between the internal and external ends when connected) to essentially eliminate any leakage when disconnecting.

Flat-face couplings and nipples that minimize oil spillage in mobile hydraulic applications up to 25 MPa. Series X65 couplings provide “clean connections” in medium-pressure applications, such as on construction equipment, agricultural machinery, and forestry equipment, by minimizing hydraulic fluid leakage that pollutes the atmosphere and hydraulic systems in which it infiltrates.
Meeting design requirements for ISO Standard 16028, Series X65 offers:
- Flat-face design: Minimizes spillage during connection and disconnection. Smooth, flat surfaces are easily wiped clean, further reducing spillage and threat of contamination.
- One-hand operation: Makes connection and disconnection fast and easy. Coupling and nipple automatically lock into place during connection.
- Manual security-locking feature: Offers added protection against involuntary disconnection
- Two-part design: Features separate front and back sections, in order to incorporate custom rear sections or threads upon request
- Optional dust caps: Recommended for use on the coupling and nipple, when connected and disconnected, to prevent debris from entering systems.
- Useful size range: Offered in ¼-inch through 1-inch sizes, making them suitable for a wide variety of applications

Threadless hose fittings that are a patented, innovative alternative to conventional threaded fitting. WEO Plug-In fittings simply “plug in” to hydraulic systems. A click-to-connect feature provides easy engagement of the male and female halves, without the tools required to connect and disconnect threaded fittings. Other benefits include:
- Leak-free connections.
- No follow-up tightening.
- Minimum space needed. A cartridge insert, designed to drop into the port or valve manifold, allows further reduction in space required for hose assemblies.
- Work injuries eliminated.
- Longer hose life: WEO fittings are self-aligning.
- Easy to service.
- Lower overall cost: Elimination of leakage, improved accessibility, and reduced installation time make WEO fittings lower in overall cost than threaded fittings.
