Some customers with 1-inch wells, can also have short water columns for which top weights are needed when using HydraSleeves.
Please see the 1-inch Top weight for the new 1-inch SkinnySleeves, which were introduced in January 2015. 
This top weight will operate in a similar fashion to the SuperSleeve top weights. The top weight is threaded onto the bottom threads of the 1-inch PVC Collar which holds the HydraSleeve in place.
Please see the assembly instructions at this link.
The 1-inch Top Weight will compress the 48-inch long 1-inch HydraSleeve to within 3 feet of the bottom of the well. It doesn't give much compression because there simply is no room for the sleeve to bunch up. Therefore, to use the 1-inch HydraSleeve with the top weight effectively you may need to use an alternate method of retrieval. The short cycle method will most likely work better than a continuous pull retrieval. See the HydraSleeve Field Manual for more information.
PLEASE NOTE: DUE TO THE DECREASED I.D. OF THE TOP WEIGHT COMPARED TO THE O.D. OF THE 1-INCH HYDRASLEEVE, CAPCACITY OF THE SLEEVE WILL BE REDUCED TO ~250MLS (MAX VOLUME) WHEN USING THE TOP WEIGHT.
Four components are necessary for the Top-weighted 1-inch HydraSleeve. Please see ordering information below:
1-inch HydraSleeve $30.00 (disposable)
PVC Collar with Clip $25.00 (reusable)
1-inch Top Weight $40.00 (reusable)
8-ounce Bottom Weight (reusable)
