ILANA DIAMOND ROVNER, Circuit Judge.
The explosion of a furnace gave rise to this personal injury suit against Mapco Gas Products, Incorporated (“Mapco”) and Honeywell, Incorporated (“Honeywell”). Honeywell, which manufactured a valve that allegedly triggered the explosion, moved for summary judgment on the plaintiffs’ product liability claims and on Mapco’s cross-claims for contribution and indemnity. The district court granted the motion, and the plaintiffs subsequently settled their remaining claims against Mapco. Mapco and the plaintiffs now appeal the summary judgment ruling in favor of Honeywell. We affirm.
I. BACKGROUND
On the morning of May 18, 1988, Ivan and Mary Avery awoke to the smell of gas in their home in rural Noble County, Indiana. Believing the odor to be a sign that their gas storage tank was empty, Ivan Avery telephoned their gas supplier, Thermo Gas Company of New Paris (“Thermo Gas”), a wholly owned subsidiary of Mapco, to report the odor and request a gas delivery. He made a similar call later in the day as did Mary Avery, who informed Mapco that the odor was stronger. A Thermo Gas employee finally arrived that evening. Although he delivered the gas as requested, the employee failed to check for a gas leak or to re-ignite the pilot lights on the home’s gas appliances. After the employee left, Mary Avery and her son, Joseph Swango, went into the home’s basement to investigate the persistent gas odor and check the furnace pilot light. When Mary Avery turned on a flashlight to inspect the furnace, the furnace exploded. She and her son suffered burns over 65 percent of their bodies. The house sustained structural damage, and some of the Averys’ personal property was destroyed. Ivan Avery claims a loss of consortium.
The Averys’ furnace was fueled by liquid petroleum (“LP”) gas, more commonly known as propane. A valve manufactured by Honeywell regulated the flow of gas into the furnace. Honeywell had recalled the valve in 1980 after concluding that it might fail to perform a critical safety function. Honeywell had determined that when the pilot flame on a furnace was extinguished, the valve might still permit gas to flow into the furnace burner when the thermostat called for heat. Whereas natural gas would be vented harmlessly through the flue, LP gas, which is heavier than air, might pool around the furnace and create the potential for an explosion. The Averys allege that this is precisely what caused their own furnace to explode.
Honeywell conducted the valve recall with the approval and oversight of the Consumer Product Safety Commission and in cooperation with LP gas suppliers like Mapco. Suppliers were asked either to supply Honeywell with a list of their customers, so that Honeywell could contact them directly or, in the alternative, to contact their customers on Honeywell’s behalf. In April 1983, Thermo Gas notified Honeywell that it had mailed recall notices to its customers with their monthly statements. Theoretically, the Averys’ predecessors should have received such a notice. However, the prior owners of the home could not recall receiving a notice, and the appropriate repairs were never made pursuant to the recall.
The Averys contend that Honeywell is liable under theories of negligence, strict liability, breach of express and implied warranties, negligent recall, and fraudulent reporting under the federal Consumer Product Safety Act. They also allege that Mapco was negligent in delivering gas to their home, inspecting the gas supply system, and in failing to warn them of the dangers attending use of LP gas. In its cross-claim, Mapco contends that it is entitled to contribution from Honeywell as a joint tort feasor and indemnity as Honeywell’s agent for purposes of the valve recall.
The district court granted summary judgment on each of the claims against Honey
