Info CenterFAQs

Can you match colors?

Colors can be matched at our in-house material formulation lab. However, we have so many standard colors available that we can typically find a standard color to work in our customer's application.

What materials do you use to make the caps and plugs?

While we use a variety of material formulations, the vinyl caps are made from Polyvinyl Chloride (PVC), the hard plastic caps are primarily Low Density Polyethylene (LDPE), and the rubber products are made from Silicone and EPDM.

What is Prop 65 labeling and how does it affect me?

Sinclair & Rush products are compliant with California Proposition 65 due to our decision to provide the appropriate warning label on our applicable products. If you utilize certain Sinclair & Rush products and do not choose to label your product according to California Proposition 65 requirements, you may find your products are not compliant with California Prop 65.  For more details, please research, read our Prop 65 statement, or contact your salesperson for further assistance.

Does StockCap have custom molding capabilities?

Yes, please call for more information on our custom capabilities. Also, it is important to note that we can usually vary the length, wall thickness and texture of a product without tooling charges.

How expensive is custom tooling?

Actual costs will vary depending on the size of the part and the number of molds that we create. Please consult one of our sales engineers for more information.

Is there a minimum order for custom projects?

Each custom project is evaluated in regards to its design complexity, annual volume and part size. Please contact one of our sales engineers for more information.

Can I return products if they do not fit?

It is very important to test samples before placing an order. All sales of production items are final. Stock items can be returned in full box quantities, but are subject to a restocking charge.

Do you have a price list?

The flexibility of the vinyl dip molding process allows for an almost infinite number of products. Consequently, we do not publish a price list. Please send us your request and we will be happy to provide a quote for the items for which you have interest.

Do you have a representative in my area?

All StockCap salespeople are trained employees of our company. Please contact our office for the salesperson who services your region.

Do you sell directly or through distributors?

We sell both directly and through distributors.

How can I set up credit with your company?

StockCap sells on Net 30 Terms with credit approval or you can pay by credit card. Download the credit application

Where is your shipping point?

Arnold, Missouri for U.S. shipments, Maidstone, Kent for European Shipments,  Riverstone, NSW for Australian shipments and Changzhou, Jiangsu, China for Asian shipments.

Can I receive a sample of a part that is not stocked?

Samples of non-stock, standard items (different color, material or length) are made in our sample lab and typically mailed within one week.

Can I receive free samples?

Samples can be provided free of charge, in most instances. We encourage the testing of any cap or plug on your application to ensure a proper fit.

How do you mail samples?

Samples are typically sent via first class mail. Priority services are available if you provide your account information.
