Item 7.01 -- Regulation FD Disclosure.

Attached as Exhibit 99.1 is a transcript of a conference call discussing IDEX
Corporation's first quarter operating results.

The Securities and Exchange Commission encourages companies to disclose
forward-looking information so that investors can better understand the future
prospects of a company and make informed investment decisions. This current
report and exhibit contain these types of statements, which are "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995.

These statements may relate to, among other things, capital expenditures, cost
reductions, cash flow, and operating improvements and are indicated by words or
phrases such as "anticipate," "estimate," "plans," "expects," "projects,"
"should," "will," "management believes," "the company believes," "the company
intends," and similar words or phrases. These statements are subject to inherent
uncertainties and risks that could cause actual results to differ materially
from those anticipated at the date of this news release. The risks and
uncertainties include, but are not limited to, the following: economic and
political consequences resulting from terrorist attacks and wars; levels of
industrial activity and economic conditions in the U.S. and other countries
around the world; pricing pressures and other competitive factors, and levels of
capital spending in certain industries -- all of which could have a material
impact on order rates and IDEX's results, particularly in light of the low
levels of order backlogs it typically maintains; its ability to make
acquisitions and to integrate and operate acquired businesses on a profitable
basis; the relationship of the U.S. dollar to other currencies and its impact on
pricing and cost competitiveness; political and economic conditions in foreign
countries in which the company operates; interest rates; capacity utilization
and the effect this has on costs; labor markets; market conditions and material
costs; and developments with respect to contingencies, such as litigation and
environmental matters. Investors are cautioned not to rely unduly on
forward-looking statements when evaluating the information presented within.

The information in this Current Report is being furnished pursuant to Items 7
and 9 and shall not be deemed "filed" for the purposes of Section 18 of the
Securities Exchange Act of 1934, as amended, or otherwise subject to the
liabilities of that Section. The information in this Current Report shall not be
incorporated by reference into any registration statement pursuant to the
Securities Act of 1933, as amended. The furnishing of the information in this
Current Report in not intended to, and does not, constitute a representation
that such furnishing is required by Regulation FD or that the information this
Current Report contains is material investor information that is not otherwise
publicly available.
