Printing and using this catalogue
Print this page from your browser to keep a copy for a shortlisting file or a line trial. The printed copy is a reference, not a controlled document. The drawing issued with a quotation is the controlled version of any part, and it is the one to attach to a purchase specification.
The range table answers the first question a buyer has, which lines exist in the neck size of their vial. The size tables then give D1 and total height to hold against the vial and stopper drawings. Pack quantities convert an order into boxes for warehouse planning: 100,000 20 mm seals, for example, is about 16.7 standard boxes of 6,000. Order quantities and lead times are set out on the MOQ and lead times page; a standard design typically starts from 50,000 pieces per size and colour, confirmed on enquiry.

Frequently asked questions
Is the Autofits catalogue available as a PDF?
The catalogue is published as this web page rather than a PDF, so the dimensions and pack quantities you read are the current ones. You can print the page from your browser. For a controlled record of a specific part, ask for its drawing, which is issued with the quotation.
Which vial seal sizes does Autofits make?
Autofits makes vial seals in 13, 20, 28, 32 and 34 mm. The FlipTop Optima covers all five sizes, the FlipTop Tear-Down and all-aluminium tear-off seal come in 13, 20 and 32 mm, the FlipTop Pull Ring in 20 and 32 mm, and the all-aluminium tear-down seal in 20 mm.
Are ROPP caps and vial seals the same sizes?
No. Vial seals are crimped over a rubber stopper on an injection vial and come in 13, 20, 28, 32 and 34 mm. ROPP caps are rolled onto the screw neck of a bottle and come in 22, 25, 28, 35 and 38 mm. The 28 mm figure appears in both ranges but refers to different neck finishes.
How many seals are in a standard box?
For FlipTop seals, a standard box of 420 × 270 × 320 mm holds 15,000 seals at 13 mm in three bags of 5,000, 6,000 at 20 mm, 3,000 at 28 mm in two bags of 1,500, and 1,400 at 32 mm in two bags of 700.
Does Autofits make custom seals outside this catalogue?
Autofits designs and develops seals in-house and customises to requirement, including colour, print and emboss. Custom work typically starts from 100,000 pieces and typically takes 4 to 6 weeks including artwork approval, both confirmed with the quotation.
