Standard Front-Mounted (Short) Wishbone Breathing Tube for Hi or Lo Press Supplied Air Regulators

These wishbone ("Y") hoses are used to connect 3M's full- and half-facepiece respirators to supplied air regulators.
They can be used for both high and low pressure supplied air (positive pressure) systems.

This product is the hose, only, and does not include a facepiece or regulator.

These hoses are included in the Wishbone Breathing Tube/Regulator Assembly Kits we sell.
See Related Products, below.

Dual airline assemblies are compatible with all 3M bayonet facepieces, as they simply attach to the bayonet fittings on the facepiece.

Standard Wishbone Air Hoses -
In most work environments, the "standard" direct-connect hoses are adequate for complete worker respiratory protection.

Combination Wishbone Air Hoses -
In some circumstances, it may be necessary to disconnect from the "house" supplied air hose in order to maneuver around an obstacle, or exit the spray booth, etc. — leaving the worker unprotected during that time.
Use of a "combination" air hose allows a connection from the belt-mounted regulator to the facepiece for positive pressure supplied air, and also has a provision on the facepiece bayonet connector to attach an appropriate filter/cartridge for self-contained negative pressure protection.
This keeps the worker protected at all times — even when temporarily disconnected from the supplied air source.
Use of a filter/cartridge is mandatory when using a "combination" hose — they won't function properly without them.
When the "house" hose to the regulator is disconnected, the system automatically changes to the installed filter/cartridges for negative pressure protection.
