BENEFITS

Snap-tite does offer a durable stackable bracket that will hold two of the 68C8-8 couplers. It is also equipped with a drain tube to carry away the small amount of spillage that occurs upon disconnection. These brackets can also be equipped with automatic dust caps that will prevent damage and contamination from dust and dirt. When the 68C8-8 is used in a bracket, body movement is required thus leading to the need for a flexible connection.


Agricultural Couplings

Featuring...Snap-tite quality and experience in the most economical package
with a range that varies from the simplest to the most sophisticated couplings.

61DC8-8 Coupler

This is a dependable and economical 1/2. ISO 7241-1 Series A coupler which has a

dual-acting sleeve. The sleeve, which has snap ring grooves that allow it to fit most industry

standard brackets, permits one-hand connect or disconnect operation. This coupler is not

designed for connection under pressure.

The coupler is made from high strength steel with zinc yellow dichromate plating for
maximum corrosion resistance. The coupler is available with the following end fittings:

61DC8-8F 1/2. Female NPSF
61DC8-8RP 1/2. Female BSP
61DC8-8EF 1/2. Female SAE
Metric threads available on request

When used in a bracket, body movement during connection or disconnection
requires the use of a flexible connection. A plastic plug (61PDP-8) is available to
prevent contamination from dust and dirt.

68C8-8 Coupler

This is a reliable, economical and versatile 1/2” ISO 7241-1 Series A coupler with a
dual-acting sleeve and connect/disconnect under pressure capability. The sleeve, which has
snap ring grooves that allow it to fit all industry standard brackets, permits one-hand connect
or disconnect operation.

A stackable bracket (68B-8) is available. This durable bracket holds two couplers and is
equipped with a drain line to carry away the small spillage that occurs on disconnection.
The bracket is designed to be stacked allowing compact installation of many couplers.
When stacked, the drain lines interconnect thus requiring only one drain connection. The
brackets can be equipped with automatic dust caps (68BC-8) which prevent damage and
contamination from dust and dirt. This coupler allows connection with pressure in either
or both the tip (nipple) and coupler. After connecting pressurized components, operation of
the vehicle’s hydraulic control valve will open the coupling valves allowing fluid to flow.
The coupler is available with the following fittings:

This is a sophisticated and rigid-mounted breakaway cartridge with easy one-hand
connect/disconnect operation and extensive features and benefits. This coupler connects to
all tips conforming to the dimensional requirements of ISO 7241-1 Series A and ISO 5675.
The coupler can be connected with pressure in either or both the tip (nipple) and
coupler. After connection, operation of the vehicle’s hydraulic control valve will open the
coupling valves thus allowing fluid to flow.
This cartridge is designed to be used in a machined manifold cavity customized to meet
customer requirements. Manifolds incorporate spillage drain connections and can be equipped
with optional automatic rubber dust caps.
