FAQs

Colors/Materials

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.

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. Learn more about How To Choose.

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.

Custom Molding

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.

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.

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.

Ordering

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.

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 Consequently, we do not publish a price list.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.
