Couplings feature novel non-spill valve design

The NS4 Series non-spill coupling features a shutoff valve that enhances operator safety and speeds connection time.

The NS4 Series non-spill coupling features a shutoff valve that enhances operator safety and speeds connection time.

The non-spill coupling provides a lightweight, durable, compact and economical replacement for expensive metal non-spill couplings, ball valves and spill-prone fittings.

The NS4 is the second in a new series of non-spill couplings introduced by Colder Products in 2003.

As a smaller version of the recently announced NSH Series non-spill coupling, the 0.25in NS4 uses a different non-spill valve design that is ideal for use in ink handling applications, chemical delivery systems, electronic cooling systems, instrumentation and medical devices.

"There is a pressing need to eliminate spills of even a few drops when customer safety, mess and clean-up, costly media loss or customer perception is an issue", said Andy Hass, Business Unit Manager, Industrial Markets at Colder Products.

"The NS4 provides a non-spill, single-click connection that enables OEMs to increase the value of their equipment by combining a small coupling size with excellent flow characteristics".

As with all CPC connection solutions, the NS4 incorporates an easy-to-use thumb latch to allow for secure, single-handed operation.

An audible "click" confirms that a secure connection is made.

The main components of the NS4 are made out of glass-filled polypropylene with 316 stainless steel springs and EPDM or optional FKM O-ring seals, which provide high resistance to a wide variety of corrosive media.

The NS4's olefinic overmoulding increases the durability of the connection and provides a better grip for users.

The overmoulding is also used for colour coding, which provides instant visual differentiation of diverse media lines.

The new non-spill connection can withstand operating pressures from vacuum to 8.3bar and temperatures from 0 to 49C.

The coupling features terminations of 0.375in OD PTF compression; 0.125, 0.25 and 0.375in ID hose barb; and 0.25in male NPT thread and 0.25in male BSPT thread.

Mounting options include inline, pipe thread and sealing panel mount.
