We accept orders by email or phone.  If you are unsure which product is correct, please give us a call to discuss your application. Relevant application information includes pipe dimensions and pressure.


Small orders, received prior to 12:00 PM (EST) for stock products, are typically shipped the same day the order is received.

Changes to display units are made at no charge and normally do not delay shipping. Other modifications carry a nominal charge and may delay shipping for one to two days.
