Description

This Flexible Swivel Hose Cuff attaches to our 2-1/2″ low loss vacuum hose.

This hose cuff thus provides a tight vacuum fit along with the ability to swivel.  A result of this swivel, users of our Post Hole Core Diggers do not experience “hose slap”. This is where the vacuum hose swings back and forth while rotating the diggers. Therefore, users of the our core diggers find that the vacuum hose with swivel works well.

Our Low Loss Vacuum Hose comes with flexible or hard cuffs.  Swivel are an accessory.

This swivel hose cuff  threads on to the exterior profile of industry standard 2.0” inner diameter crush proof hose.  This hose measures 2.0” on the inner diameter. The 2.0” slip end of the hose cuff can rotate 360 degrees independently of the thread end allowing for easier use. As a result of this unique design rotation around one point helps to reduce kinking.  This also reduces stress being placed on the vacuum hose.

Unique design coupled with the right material makes a better part.

This flexible swivel hose cuff is molded using an 85-90 shore PVC.  As a result of this material,  the threads engaging the hose providing a degree of flexibility,  The resulting flexibility accommodates minor variation in the pitch and spacing of the hose corrugations. Because of best practices design the left hand thread pattern, typical of spiral wound hoses, allows for easy engagement of the hose.  Because of this, the cuff holds secure against stripping from the hose. Therefore the rotating 2” diameter slip end is 2.25” in length.  It has a stop shoulder preventing a male end from extending into the hose where it might cause damage. The stop shoulder helps insure a smooth transition of the air stream into the hose.  In short, air flow losses are kept to a minimum.
