SpinPerfect Orifice Bars feature a NEW Tube-Hook system. This is a highly recommended orifice for spinning fine weight yarns.

• This is a bypassable tube perfect for streamlining spinning fine yarns.

• The orifice hook is in the shape of a tube.

• This orifice bar is engineered for spinning fine yarn only. Yarns under chunky weight will fit thru the orifice hole. These orifice bars are not recommended for bulky or art yarns.

• As you spin, the yarn is held close to the center of the bar so the spinning is very smooth.

SpinPerfect Perfect Tube Orifice Bars are compatible with SpinOlution spinning wheels.

Please check your flyer rod size if you are ordering the 8 oz, 16 oz, or 32 oz Perfect Tube orifice bar to make sure you order the correct fit (1/4” or 3/8” diameter flyer rod). The 1/4” diameter flyer rod is about as thick as a #2 pencil. The 3/8” diameter flyer rod is much bigger than a pencil. All 4 oz and 12 oz bobbins are 1/4”.
