Product details
The Raypak 008259F is a flange nut kit of 24 individual 1/4-20 UNC nuts used to secure the capron headers on the heat exchanger of Raypak R185B, R265A, R335A and R405A digital pool heaters.
What it does
The flange nuts hold the capron headers against the heat exchanger. Replacing them whenever the headers come off keeps the clamping hardware matched and the joint tight, and it is a common companion to header gaskets and O-ring gaskets.
Fit and compatibility
This kit is listed for the Raypak R185B, R265A, R335A and R405A digital pool heaters. The thread is 1/4-20 UNC, and the kit holds 24 nuts, enough for the set of headers on the heat exchanger. Parts diagrams for the RP2100 digital gas models R185A through R405B, the 206A, 266A, 336A and 406A atmospheric gas heaters and the 207A, 267A, 337A and 407A Low NOx heaters include the part.
Before you order
Confirm the model number on the rating plate of your heater, and confirm that the heat exchanger has capron headers. This listing is the nut kit only and does not include gaskets.
