This part has some very soft plastic. It does not come with an oring but the original oring worked just fine. Don't over tighten or it will not seal exactly on the o-ring. I noticed this mistake when I heard the hissing and it would stop when I adjusted the tightness back a full turn. Got the part tightened properly and it was actually in the same spot as the original. No hissing no leaks coming out, which would've been noticeable with all the green dye in it. So far the part appears to be working just fine.

The A/C on this truck would occasionally not turn on, and other times would work perfectly. I had checked the A/C charge with proper gauges, and it was reading in the appropriate ranges. After replacing this switch, the A/C now turns on every time, no problem. Cheap and easy fix. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/13170382-4-seasons-37308-a-c-clutch-cycle-pressure-switch-fitting](https://www.desertcart.sg/products/13170382-4-seasons-37308-a-c-clutch-cycle-pressure-switch-fitting) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-29*
