PRC Desoto - Fuel Tank Sealant - PR-1776M Class B Low Weight - Pint
PR-1776M Class B is a low density, high temperature aircraft integral fuel tank sealant. It has a service temperature range from -65-F (-54-C) to 250-F (121-C), with very limited excursions up to 360-F (182-C). This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. It offers as much as a twenty percent weight savings, per unit volume, over traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to diphosphate ester based hydraulic fluids.
PR-1776M Class B is a two-part, manganese dioxide cured Permapol- P-5 modified polysulfide. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
PR-1776M Class B is designed to be a direct replacement for PR-1776 Class B. The following tests are in accordance with AMS-3281 and BMS 5-45 specification test methods.

This is an excellent product and exactly what I needed to complete a critical fuel tank (gasoline) leak to save a classic boat from the scrap heap. A great price and the best service I can imagine. I have 30 years experience in aviation and used this product many times, didn't even know it was available, then I found Pilots HQ...so very happy to find Pilots HQ and the insurance company is happy as well. I will be back.
These sunglasses were a gift to our grandson. He is a fairly new pilot and wanted these sunglasses as a birthday gift. He is very happy with them.
The staff at Pilots HQ were great to deal with and managed pto get the sunglasses to me just in time for our grandson’s birthday.
Thanks for the help.
Heard about Boelube for years. Finally had a chance to try it on several projects. It definitely works well and better than anything else I have ever tried. Would recommend.
